Bundling your work together

-git for CVS users
-=================
-
-Git differs from CVS in that every working tree contains a repository with
-a full copy of the project history, and no repository is inherently more
-important than any other. However, you can emulate the CVS model by
-designating a single shared repository which people can synchronize with;
-this document explains how to do that.
-
-Some basic familiarity with git is required. This
-link:tutorial.html[tutorial introduction to git] and the
-link:glossary.html[git glossary] should be sufficient.
-
-Developing against a shared repository
---------------------------------------
-
-Suppose a shared repository is set up in /pub/repo.git on the host
-foo.com. Then as an individual committer you can clone the shared
-repository over ssh with:
-
-------------------------------------------------
-$ git clone foo.com:/pub/repo.git/ my-project
-$ cd my-project
-------------------------------------------------
-
-and hack away. The equivalent of `cvs update` is
-
-------------------------------------------------
-$ git pull origin
-------------------------------------------------
-
-which merges in any work that others might have done since the clone
-operation. If there are uncommitted changes in your working tree, commit
-them first before running git pull.
-
-[NOTE]
-================================
-The `pull` command knows where to get updates from because of certain
-configuration variables that were set by the first `git clone`
-command; see `git config -l` and the linkgit:git-config[1] man
-page for details.
-================================
-
-You can update the shared repository with your changes by first committing
-your changes, and then using the linkgit:git-push[1] command:
-
-------------------------------------------------
-$ git push origin master
-------------------------------------------------
-
-to "push" those commits to the shared repository. If someone else has
-updated the repository more recently, `git push`, like `cvs commit`, will
-complain, in which case you must pull any changes before attempting the
-push again.
-
-In the `git push` command above we specify the name of the remote branch
-to update (`master`). If we leave that out, `git push` tries to update
-any branches in the remote repository that have the same name as a branch
-in the local repository. So the last `push` can be done with either of:
-
-------------
-$ git push origin
-$ git push foo.com:/pub/project.git/
-------------
-
-as long as the shared repository does not have any branches
-other than `master`.
-
-Setting Up a Shared Repository
-------------------------------
-
-We assume you have already created a git repository for your project,
-possibly created from scratch or from a tarball (see the
-link:tutorial.html[tutorial]), or imported from an already existing CVS
-repository (see the next section).
-
-Assume your existing repo is at /home/alice/myproject. Create a new "bare"
-repository (a repository without a working tree) and fetch your project into
-it:
-
-------------------------------------------------
-$ mkdir /pub/my-repo.git
-$ cd /pub/my-repo.git
-$ git --bare init --shared
-$ git --bare fetch /home/alice/myproject master:master
-------------------------------------------------
-
-Next, give every team member read/write access to this repository. One
-easy way to do this is to give all the team members ssh access to the
-machine where the repository is hosted. If you don't want to give them a
-full shell on the machine, there is a restricted shell which only allows
-users to do git pushes and pulls; see linkgit:git-shell[1].
-
-Put all the committers in the same group, and make the repository
-writable by that group:
-
-------------------------------------------------
-$ chgrp -R $group /pub/my-repo.git
-------------------------------------------------
-
-Make sure committers have a umask of at most 027, so that the directories
-they create are writable and searchable by other group members.
-
-Importing a CVS archive
------------------------
-
-First, install version 2.1 or higher of cvsps from
-link:http://www.cobite.com/cvsps/[http://www.cobite.com/cvsps/] and make
-sure it is in your path. Then cd to a checked out CVS working directory
-of the project you are interested in and run linkgit:git-cvsimport[1]:
-
--------------------------------------------
-$ git cvsimport -C <destination> <module>
--------------------------------------------
-
-This puts a git archive of the named CVS module in the directory
-<destination>, which will be created if necessary.
-
-The import checks out from CVS every revision of every file. Reportedly
-cvsimport can average some twenty revisions per second, so for a
-medium-sized project this should not take more than a couple of minutes.
-Larger projects or remote repositories may take longer.
-
-The main trunk is stored in the git branch named `origin`, and additional
-CVS branches are stored in git branches with the same names. The most
-recent version of the main trunk is also left checked out on the `master`
-branch, so you can start adding your own changes right away.
-
-The import is incremental, so if you call it again next month it will
-fetch any CVS updates that have been made in the meantime. For this to
-work, you must not modify the imported branches; instead, create new
-branches for your own changes, and merge in the imported branches as
-necessary.
-
-Advanced Shared Repository Management
--------------------------------------
-
-Git allows you to specify scripts called "hooks" to be run at certain
-points. You can use these, for example, to send all commits to the shared
-repository to a mailing list. See linkgit:githooks[5][Hooks used by git].
-
-You can enforce finer grained permissions using update hooks. See
-link:howto/update-hook-example.txt[Controlling access to branches using
-update hooks].
-
-Providing CVS Access to a git Repository
-----------------------------------------
-
-It is also possible to provide true CVS access to a git repository, so
-that developers can still use CVS; see linkgit:git-cvsserver[1] for
-details.
-
-Alternative Development Models
-------------------------------
-
-CVS users are accustomed to giving a group of developers commit access to
-a common repository. As we've seen, this is also possible with git.
-However, the distributed nature of git allows other development models,
-and you may want to first consider whether one of them might be a better
-fit for your project.
-
-For example, you can choose a single person to maintain the project's
-primary public repository. Other developers then clone this repository
-and each work in their own clone. When they have a series of changes that
-they're happy with, they ask the maintainer to pull from the branch
-containing the changes. The maintainer reviews their changes and pulls
-them into the primary repository, which other developers pull from as
-necessary to stay coordinated. The Linux kernel and other projects use
-variants of this model.
-
-With a small group, developers may just pull changes from each other's
-repositories without the need for a central maintainer.

+'git-cvsexportcommit' [-h] [-u] [-v] [-c] [-P] [-p] [-a] [-d cvsroot] [-w cvsworkdir] [-W] [-f] [-m msgprefix] [PARENTCOMMIT] COMMITID
DESCRIPTION
current directory is within a git repository. The default is the
value of 'cvsexportcommit.cvsdir'.
+-W::
+ Tell cvsexportcommit that the current working directory is not only
+ a Git checkout, but also the CVS checkout. Therefore, Git will
+ reset the working directory to the parent commit before proceeding.
+
-v::
Verbose.
Legacy monitoring operations are not supported (edit, watch and related).
Exports and tagging (tags and branches) are not supported at this stage.
-The server should set the '-k' mode to binary when relevant, however,
-this is not really implemented yet. For now, you can force the server
-to set '-kb' for all files by setting the `gitcvs.allbinary` config
-variable. In proper GIT tradition, the contents of the files are
-always respected. No keyword expansion or newline munging is supported.
+CRLF Line Ending Conversions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default the server leaves the '-k' mode blank for all files,
+which causes the cvs client to treat them as a text files, subject
+to crlf conversion on some platforms.
+
+You can make the server use `crlf` attributes to set the '-k' modes
+for files by setting the `gitcvs.usecrlfattr` config variable.
+In this case, if `crlf` is explicitly unset ('-crlf'), then the
+server will set '-kb' mode for binary files. If `crlf` is set,
+then the '-k' mode will explicitly be left blank. See
+also linkgit:gitattributes[5] for more information about the `crlf`
+attribute.
+
+Alternatively, if `gitcvs.usecrlfattr` config is not enabled
+or if the `crlf` attribute is unspecified for a filename, then
+the server uses the `gitcvs.allbinary` config for the default setting.
+If `gitcvs.allbinary` is set, then file not otherwise
+specified will default to '-kb' mode. Otherwise the '-k' mode
+is left blank. But if `gitcvs.allbinary` is set to "guess", then
+the correct '-k' mode will be guessed based on the contents of
+the file.
+
+For best consistency with cvs, it is probably best to override the
+defaults by setting `gitcvs.usecrlfattr` to true,
+and `gitcvs.allbinary` to "guess".

+================
+
+NAME
+----
+gittutorial-2 - A tutorial introduction to git: part two
+
+SYNOPSIS
+--------
+git *
+
+DESCRIPTION
+-----------
+
+You should work through linkgit:gittutorial[7][A tutorial introduction to
+git] before reading this tutorial.
+
+The goal of this tutorial is to introduce two fundamental pieces of
+git's architecture--the object database and the index file--and to
+provide the reader with everything necessary to understand the rest
+of the git documentation.
+
+The git object database
+-----------------------
+
+Let's start a new project and create a small amount of history:
+
+------------------------------------------------
+$ mkdir test-project
+$ cd test-project
+$ git init
+Initialized empty Git repository in .git/
+$ echo 'hello world' > file.txt
+$ git add .
+$ git commit -a -m "initial commit"
+Created initial commit 54196cc2703dc165cbd373a65a4dcf22d50ae7f7
+ create mode 100644 file.txt
+$ echo 'hello world!' >file.txt
+$ git commit -a -m "add emphasis"
+Created commit c4d59f390b9cfd4318117afde11d601c1085f241
+------------------------------------------------
+
+What are the 40 digits of hex that git responded to the commit with?
+
+We saw in part one of the tutorial that commits have names like this.
+It turns out that every object in the git history is stored under
+such a 40-digit hex name. That name is the SHA1 hash of the object's
+contents; among other things, this ensures that git will never store
+the same data twice (since identical data is given an identical SHA1
+name), and that the contents of a git object will never change (since
+that would change the object's name as well).
+
+It is expected that the content of the commit object you created while
+following the example above generates a different SHA1 hash than
+the one shown above because the commit object records the time when
+it was created and the name of the person performing the commit.
+
+We can ask git about this particular object with the cat-file
+command. Don't copy the 40 hex digits from this example but use those
+from your own version. Note that you can shorten it to only a few
+characters to save yourself typing all 40 hex digits:
+
+------------------------------------------------
+$ git-cat-file -t 54196cc2
+commit
+$ git-cat-file commit 54196cc2
+tree 92b8b694ffb1675e5975148e1121810081dbdffe

+------------------------------------------------
+
+A tree can refer to one or more "blob" objects, each corresponding to
+a file. In addition, a tree can also refer to other tree objects,
+thus creating a directory hierarchy. You can examine the contents of
+any tree using ls-tree (remember that a long enough initial portion
+of the SHA1 will also work):
+

+------------------------------------------------
+
+Thus we see that this tree has one file in it. The SHA1 hash is a
+reference to that file's data:
+
+------------------------------------------------
+$ git cat-file -t 3b18e512
+blob
+------------------------------------------------
+
+A "blob" is just file data, which we can also examine with cat-file:
+
+------------------------------------------------
+$ git cat-file blob 3b18e512
+hello world
+------------------------------------------------
+
+Note that this is the old file data; so the object that git named in
+its response to the initial tree was a tree with a snapshot of the
+directory state that was recorded by the first commit.
+
+All of these objects are stored under their SHA1 names inside the git
+directory:
+
+------------------------------------------------
+$ find .git/objects/
+.git/objects/
+.git/objects/pack
+.git/objects/info
+.git/objects/3b
+.git/objects/3b/18e512dba79e4c8300dd08aeb37f8e728b8dad
+.git/objects/92
+.git/objects/92/b8b694ffb1675e5975148e1121810081dbdffe
+.git/objects/54
+.git/objects/54/196cc2703dc165cbd373a65a4dcf22d50ae7f7
+.git/objects/a0
+.git/objects/a0/423896973644771497bdc03eb99d5281615b51

+.git/objects/d0/492b368b66bdabf2ac1fd8c92b39d3db916e59
+.git/objects/c4
+.git/objects/c4/d59f390b9cfd4318117afde11d601c1085f241
+------------------------------------------------
+
+and the contents of these files is just the compressed data plus a
+header identifying their length and their type. The type is either a
+blob, a tree, a commit, or a tag.
+
+The simplest commit to find is the HEAD commit, which we can find
+from .git/HEAD:
+
+------------------------------------------------
+$ cat .git/HEAD
+ref: refs/heads/master
+------------------------------------------------
+
+As you can see, this tells us which branch we're currently on, and it
+tells us this by naming a file under the .git directory, which itself
+contains a SHA1 name referring to a commit object, which we can
+examine with cat-file:
+
+------------------------------------------------
+$ cat .git/refs/heads/master
+c4d59f390b9cfd4318117afde11d601c1085f241
+$ git cat-file -t c4d59f39
+commit
+$ git cat-file commit c4d59f39
+tree d0492b368b66bdabf2ac1fd8c92b39d3db916e59
+parent 54196cc2703dc165cbd373a65a4dcf22d50ae7f7
+author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143418702 -0500
+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143418702 -0500
+
+add emphasis
+------------------------------------------------
+
+The "tree" object here refers to the new state of the tree:
+
+------------------------------------------------
+$ git ls-tree d0492b36
+100644 blob a0423896973644771497bdc03eb99d5281615b51 file.txt
+$ git cat-file blob a0423896
+hello world!
+------------------------------------------------
+
+and the "parent" object refers to the previous commit:
+
+------------------------------------------------
+$ git-cat-file commit 54196cc2
+tree 92b8b694ffb1675e5975148e1121810081dbdffe
+author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+
+initial commit
+------------------------------------------------
+
+The tree object is the tree we examined first, and this commit is
+unusual in that it lacks any parent.
+
+Most commits have only one parent, but it is also common for a commit
+to have multiple parents. In that case the commit represents a
+merge, with the parent references pointing to the heads of the merged
+branches.
+
+Besides blobs, trees, and commits, the only remaining type of object
+is a "tag", which we won't discuss here; refer to linkgit:git-tag[1]
+for details.
+
+So now we know how git uses the object database to represent a
+project's history:
+
+ * "commit" objects refer to "tree" objects representing the
+ snapshot of a directory tree at a particular point in the
+ history, and refer to "parent" commits to show how they're
+ connected into the project history.
+ * "tree" objects represent the state of a single directory,
+ associating directory names to "blob" objects containing file
+ data and "tree" objects containing subdirectory information.
+ * "blob" objects contain file data without any other structure.
+ * References to commit objects at the head of each branch are
+ stored in files under .git/refs/heads/.
+ * The name of the current branch is stored in .git/HEAD.
+
+Note, by the way, that lots of commands take a tree as an argument.
+But as we can see above, a tree can be referred to in many different
+ways--by the SHA1 name for that tree, by the name of a commit that
+refers to the tree, by the name of a branch whose head refers to that
+tree, etc.--and most such commands can accept any of these names.
+
+In command synopses, the word "tree-ish" is sometimes used to
+designate such an argument.
+
+The index file
+--------------
+
+The primary tool we've been using to create commits is "git commit
+-a", which creates a commit including every change you've made to
+your working tree. But what if you want to commit changes only to
+certain files? Or only certain changes to certain files?
+
+If we look at the way commits are created under the cover, we'll see
+that there are more flexible ways creating commits.
+
+Continuing with our test-project, let's modify file.txt again:
+
+------------------------------------------------
+$ echo "hello world, again" >>file.txt
+------------------------------------------------
+
+but this time instead of immediately making the commit, let's take an
+intermediate step, and ask for diffs along the way to keep track of
+what's happening:
+
+------------------------------------------------
+$ git diff
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+$ git add file.txt
+$ git diff
+------------------------------------------------
+
+The last diff is empty, but no new commits have been made, and the
+head still doesn't contain the new line:
+
+------------------------------------------------
+$ git-diff HEAD
+diff --git a/file.txt b/file.txt
+index a042389..513feba 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+------------------------------------------------
+
+So "git diff" is comparing against something other than the head.
+The thing that it's comparing against is actually the index file,
+which is stored in .git/index in a binary format, but whose contents
+we can examine with ls-files:
+
+------------------------------------------------
+$ git ls-files --stage
+100644 513feba2e53ebbd2532419ded848ba19de88ba00 0 file.txt
+$ git cat-file -t 513feba2
+blob
+$ git cat-file blob 513feba2
+hello world!
+hello world, again
+------------------------------------------------
+
+So what our "git add" did was store a new blob and then put
+a reference to it in the index file. If we modify the file again,
+we'll see that the new modifications are reflected in the "git-diff"
+output:
+
+------------------------------------------------
+$ echo 'again?' >>file.txt
+$ git diff
+index 513feba..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1,2 +1,3 @@
+ hello world!
+ hello world, again
++again?
+------------------------------------------------
+
+With the right arguments, git diff can also show us the difference
+between the working directory and the last commit, or between the
+index and the last commit:
+
+------------------------------------------------
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index a042389..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,3 @@
+ hello world!
++hello world, again
++again?
+$ git diff --cached
+diff --git a/file.txt b/file.txt
+index a042389..513feba 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+------------------------------------------------
+
+At any time, we can create a new commit using "git commit" (without
+the -a option), and verify that the state committed only includes the
+changes stored in the index file, not the additional change that is
+still only in our working tree:
+
+------------------------------------------------
+$ git commit -m "repeat"
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index 513feba..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1,2 +1,3 @@
+ hello world!
+ hello world, again
++again?
+------------------------------------------------
+
+So by default "git commit" uses the index to create the commit, not
+the working tree; the -a option to commit tells it to first update
+the index with all changes in the working tree.
+
+Finally, it's worth looking at the effect of "git add" on the index
+file:
+
+------------------------------------------------
+$ echo "goodbye, world" >closing.txt
+$ git add closing.txt
+------------------------------------------------
+
+The effect of the "git add" was to add one entry to the index file:
+
+------------------------------------------------
+$ git ls-files --stage
+100644 8b9743b20d4b15be3955fc8d5cd2b09cd2336138 0 closing.txt
+100644 513feba2e53ebbd2532419ded848ba19de88ba00 0 file.txt
+------------------------------------------------
+
+And, as you can see with cat-file, this new entry refers to the
+current contents of the file:
+
+------------------------------------------------
+$ git cat-file blob 8b9743b2
+goodbye, world
+------------------------------------------------
+
+The "status" command is a useful way to get a quick summary of the
+situation:
+
+------------------------------------------------
+$ git status
+# On branch master
+# Changes to be committed:
+# (use "git reset HEAD <file>..." to unstage)
+#
+# new file: closing.txt
+#
+# Changed but not updated:
+# (use "git add <file>..." to update what will be committed)
+#
+# modified: file.txt
+#
+------------------------------------------------
+
+Since the current state of closing.txt is cached in the index file,
+it is listed as "Changes to be committed". Since file.txt has
+changes in the working directory that aren't reflected in the index,
+it is marked "changed but not updated". At this point, running "git
+commit" would create a commit that added closing.txt (with its new
+contents), but that didn't modify file.txt.
+
+Also, note that a bare "git diff" shows the changes to file.txt, but
+not the addition of closing.txt, because the version of closing.txt
+in the index file is identical to the one in the working directory.
+
+In addition to being the staging area for new commits, the index file
+is also populated from the object database when checking out a
+branch, and is used to hold the trees involved in a merge operation.
+See the link:core-tutorial.html[core tutorial] and the relevant man
+pages for details.

+----------
+
+At this point you should know everything necessary to read the man

+should be able to find any unknown jargon in the
+link:glossary.html[Glossary].

+The link:user-manual.html[Git User's Manual] provides a more
+comprehensive introduction to git.

+The linkgit:gitcvs-migration[7][CVS migration] document explains how to
+import a CVS repository into git, and shows how to use git in a
+CVS-like way.

+NAME
+----
+gittutorial - A tutorial introduction to git (for version 1.5.1 or newer)
+
+SYNOPSIS
+--------
+git *
+
+DESCRIPTION
+-----------
+
+This tutorial explains how to import a new project into git, make
+changes to it, and share changes with other developers.
+
+If you are instead primarily interested in using git to fetch a project,
+for example, to test the latest version, you may prefer to start with
+the first two chapters of link:user-manual.html[The Git User's Manual].
+
+First, note that you can get documentation for a command such as "git
+diff" with:
+
+------------------------------------------------
+$ man git-diff
+------------------------------------------------
+
+It is a good idea to introduce yourself to git with your name and
+public email address before doing any operation. The easiest
+way to do so is:
+
+------------------------------------------------
+$ git config --global user.name "Your Name Comes Here"
+$ git config --global user.email you@yourdomain.example.com
+------------------------------------------------
+
+
+Importing a new project
+-----------------------
+
+Assume you have a tarball project.tar.gz with your initial work. You
+can place it under git revision control as follows.
+
+------------------------------------------------
+$ tar xzf project.tar.gz
+$ cd project
+$ git init
+------------------------------------------------
+
+Git will reply
+
+------------------------------------------------
+Initialized empty Git repository in .git/
+------------------------------------------------
+
+You've now initialized the working directory--you may notice a new
+directory created, named ".git".
+
+Next, tell git to take a snapshot of the contents of all files under the
+current directory (note the '.'), with linkgit:git-add[1]:
+
+------------------------------------------------
+$ git add .
+------------------------------------------------
+
+This snapshot is now stored in a temporary staging area which git calls
+the "index". You can permanently store the contents of the index in the
+repository with linkgit:git-commit[1]:
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+This will prompt you for a commit message. You've now stored the first
+version of your project in git.
+
+Making changes
+--------------
+
+Modify some files, then add their updated contents to the index:
+
+------------------------------------------------
+$ git add file1 file2 file3
+------------------------------------------------
+
+You are now ready to commit. You can see what is about to be committed
+using linkgit:git-diff[1] with the --cached option:
+
+------------------------------------------------
+$ git diff --cached
+------------------------------------------------
+
+(Without --cached, linkgit:git-diff[1] will show you any changes that
+you've made but not yet added to the index.) You can also get a brief
+summary of the situation with linkgit:git-status[1]:
+
+------------------------------------------------
+$ git status
+# On branch master
+# Changes to be committed:
+# (use "git reset HEAD <file>..." to unstage)
+#
+# modified: file1
+# modified: file2
+# modified: file3
+#
+------------------------------------------------
+
+If you need to make any further adjustments, do so now, and then add any
+newly modified content to the index. Finally, commit your changes with:
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+This will again prompt your for a message describing the change, and then
+record a new version of the project.
+
+Alternatively, instead of running `git add` beforehand, you can use
+
+------------------------------------------------
+$ git commit -a
+------------------------------------------------
+
+which will automatically notice any modified (but not new) files, add
+them to the index, and commit, all in one step.
+
+A note on commit messages: Though not required, it's a good idea to
+begin the commit message with a single short (less than 50 character)
+line summarizing the change, followed by a blank line and then a more
+thorough description. Tools that turn commits into email, for
+example, use the first line on the Subject: line and the rest of the
+commit in the body.
+
+Git tracks content not files
+----------------------------
+
+Many revision control systems provide an "add" command that tells the
+system to start tracking changes to a new file. Git's "add" command
+does something simpler and more powerful: `git add` is used both for new
+and newly modified files, and in both cases it takes a snapshot of the
+given files and stages that content in the index, ready for inclusion in
+the next commit.
+
+Viewing project history
+-----------------------
+
+At any point you can view the history of your changes using
+
+------------------------------------------------
+$ git log
+------------------------------------------------
+
+If you also want to see complete diffs at each step, use
+
+------------------------------------------------
+$ git log -p
+------------------------------------------------
+
+Often the overview of the change is useful to get a feel of
+each step
+
+------------------------------------------------
+$ git log --stat --summary
+------------------------------------------------
+
+Managing branches
+-----------------
+
+A single git repository can maintain multiple branches of
+development. To create a new branch named "experimental", use
+
+------------------------------------------------
+$ git branch experimental
+------------------------------------------------
+
+If you now run
+
+------------------------------------------------
+$ git branch
+------------------------------------------------
+
+you'll get a list of all existing branches:
+
+------------------------------------------------
+ experimental
+* master
+------------------------------------------------
+
+The "experimental" branch is the one you just created, and the
+"master" branch is a default branch that was created for you
+automatically. The asterisk marks the branch you are currently on;
+type
+
+------------------------------------------------
+$ git checkout experimental
+------------------------------------------------
+
+to switch to the experimental branch. Now edit a file, commit the
+change, and switch back to the master branch:
+
+------------------------------------------------
+(edit file)
+$ git commit -a
+$ git checkout master
+------------------------------------------------
+
+Check that the change you made is no longer visible, since it was
+made on the experimental branch and you're back on the master branch.
+
+You can make a different change on the master branch:
+
+------------------------------------------------
+(edit file)
+$ git commit -a
+------------------------------------------------
+
+at this point the two branches have diverged, with different changes
+made in each. To merge the changes made in experimental into master, run
+
+------------------------------------------------
+$ git merge experimental
+------------------------------------------------
+
+If the changes don't conflict, you're done. If there are conflicts,
+markers will be left in the problematic files showing the conflict;
+
+------------------------------------------------
+$ git diff
+------------------------------------------------
+
+will show this. Once you've edited the files to resolve the
+conflicts,
+
+------------------------------------------------
+$ git commit -a
+------------------------------------------------
+
+will commit the result of the merge. Finally,
+
+------------------------------------------------
+$ gitk
+------------------------------------------------
+
+will show a nice graphical representation of the resulting history.
+
+At this point you could delete the experimental branch with
+
+------------------------------------------------
+$ git branch -d experimental
+------------------------------------------------
+
+This command ensures that the changes in the experimental branch are
+already in the current branch.
+
+If you develop on a branch crazy-idea, then regret it, you can always
+delete the branch with
+
+-------------------------------------
+$ git branch -D crazy-idea
+-------------------------------------
+
+Branches are cheap and easy, so this is a good way to try something
+out.
+
+Using git for collaboration
+---------------------------
+
+Suppose that Alice has started a new project with a git repository in
+/home/alice/project, and that Bob, who has a home directory on the
+same machine, wants to contribute.
+
+Bob begins with:
+
+------------------------------------------------
+$ git clone /home/alice/project myrepo
+------------------------------------------------
+
+This creates a new directory "myrepo" containing a clone of Alice's
+repository. The clone is on an equal footing with the original
+project, possessing its own copy of the original project's history.
+
+Bob then makes some changes and commits them:
+
+------------------------------------------------
+(edit files)
+$ git commit -a
+(repeat as necessary)
+------------------------------------------------
+
+When he's ready, he tells Alice to pull changes from the repository
+at /home/bob/myrepo. She does this with:
+
+------------------------------------------------
+$ cd /home/alice/project
+$ git pull /home/bob/myrepo master
+------------------------------------------------
+
+This merges the changes from Bob's "master" branch into Alice's
+current branch. If Alice has made her own changes in the meantime,
+then she may need to manually fix any conflicts. (Note that the
+"master" argument in the above command is actually unnecessary, as it
+is the default.)
+
+The "pull" command thus performs two operations: it fetches changes
+from a remote branch, then merges them into the current branch.
+
+When you are working in a small closely knit group, it is not
+unusual to interact with the same repository over and over
+again. By defining 'remote' repository shorthand, you can make
+it easier:
+
+------------------------------------------------
+$ git remote add bob /home/bob/myrepo
+------------------------------------------------
+
+With this, Alice can perform the first operation alone using the
+"git fetch" command without merging them with her own branch,
+using:
+
+-------------------------------------
+$ git fetch bob
+-------------------------------------
+
+Unlike the longhand form, when Alice fetches from Bob using a
+remote repository shorthand set up with `git remote`, what was
+fetched is stored in a remote tracking branch, in this case
+`bob/master`. So after this:
+
+-------------------------------------
+$ git log -p master..bob/master
+-------------------------------------
+
+shows a list of all the changes that Bob made since he branched from
+Alice's master branch.
+
+After examining those changes, Alice
+could merge the changes into her master branch:
+
+-------------------------------------
+$ git merge bob/master
+-------------------------------------
+
+This `merge` can also be done by 'pulling from her own remote
+tracking branch', like this:
+
+-------------------------------------
+$ git pull . remotes/bob/master
+-------------------------------------
+
+Note that git pull always merges into the current branch,
+regardless of what else is given on the command line.
+
+Later, Bob can update his repo with Alice's latest changes using
+
+-------------------------------------
+$ git pull
+-------------------------------------
+
+Note that he doesn't need to give the path to Alice's repository;
+when Bob cloned Alice's repository, git stored the location of her
+repository in the repository configuration, and that location is
+used for pulls:
+
+-------------------------------------
+$ git config --get remote.origin.url
+/home/alice/project
+-------------------------------------
+
+(The complete configuration created by git-clone is visible using
+"git config -l", and the linkgit:git-config[1] man page
+explains the meaning of each option.)
+
+Git also keeps a pristine copy of Alice's master branch under the
+name "origin/master":
+
+-------------------------------------
+$ git branch -r
+ origin/master
+-------------------------------------
+
+If Bob later decides to work from a different host, he can still
+perform clones and pulls using the ssh protocol:
+
+-------------------------------------
+$ git clone alice.org:/home/alice/project myrepo
+-------------------------------------
+
+Alternatively, git has a native protocol, or can use rsync or http;
+see linkgit:git-pull[1] for details.
+
+Git can also be used in a CVS-like mode, with a central repository
+that various users push changes to; see linkgit:git-push[1] and
+linkgit:gitcvs-migration[7][git for CVS users].
+
+Exploring history
+-----------------
+
+Git history is represented as a series of interrelated commits. We
+have already seen that the git log command can list those commits.
+Note that first line of each git log entry also gives a name for the
+commit:
+
+-------------------------------------
+$ git log
+commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+Author: Junio C Hamano <junkio@cox.net>
+Date: Tue May 16 17:18:22 2006 -0700
+
+ merge-base: Clarify the comments on post processing.
+-------------------------------------
+
+We can give this name to git show to see the details about this
+commit.
+
+-------------------------------------
+$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+-------------------------------------
+
+But there are other ways to refer to commits. You can use any initial
+part of the name that is long enough to uniquely identify the commit:
+
+-------------------------------------
+$ git show c82a22c39c # the first few characters of the name are
+ # usually enough
+$ git show HEAD # the tip of the current branch
+$ git show experimental # the tip of the "experimental" branch
+-------------------------------------
+
+Every commit usually has one "parent" commit
+which points to the previous state of the project:
+
+-------------------------------------
+$ git show HEAD^ # to see the parent of HEAD
+$ git show HEAD^^ # to see the grandparent of HEAD
+$ git show HEAD~4 # to see the great-great grandparent of HEAD
+-------------------------------------
+
+Note that merge commits may have more than one parent:
+
+-------------------------------------
+$ git show HEAD^1 # show the first parent of HEAD (same as HEAD^)
+$ git show HEAD^2 # show the second parent of HEAD
+-------------------------------------
+
+You can also give commits names of your own; after running
+
+-------------------------------------
+$ git-tag v2.5 1b2e1d63ff
+-------------------------------------
+
+you can refer to 1b2e1d63ff by the name "v2.5". If you intend to
+share this name with other people (for example, to identify a release
+version), you should create a "tag" object, and perhaps sign it; see
+linkgit:git-tag[1] for details.
+
+Any git command that needs to know a commit can take any of these
+names. For example:
+
+-------------------------------------
+$ git diff v2.5 HEAD # compare the current HEAD to v2.5
+$ git branch stable v2.5 # start a new branch named "stable" based
+ # at v2.5
+$ git reset --hard HEAD^ # reset your current branch and working
+ # directory to its state at HEAD^
+-------------------------------------
+
+Be careful with that last command: in addition to losing any changes
+in the working directory, it will also remove all later commits from
+this branch. If this branch is the only branch containing those
+commits, they will be lost. Also, don't use "git reset" on a
+publicly-visible branch that other developers pull from, as it will
+force needless merges on other developers to clean up the history.
+If you need to undo changes that you have pushed, use linkgit:git-revert[1]
+instead.
+
+The git grep command can search for strings in any version of your
+project, so
+
+-------------------------------------
+$ git grep "hello" v2.5
+-------------------------------------
+
+searches for all occurrences of "hello" in v2.5.
+
+If you leave out the commit name, git grep will search any of the
+files it manages in your current directory. So
+
+-------------------------------------
+$ git grep "hello"
+-------------------------------------
+
+is a quick way to search just the files that are tracked by git.
+
+Many git commands also take sets of commits, which can be specified
+in a number of ways. Here are some examples with git log:
+
+-------------------------------------
+$ git log v2.5..v2.6 # commits between v2.5 and v2.6
+$ git log v2.5.. # commits since v2.5
+$ git log --since="2 weeks ago" # commits from the last 2 weeks
+$ git log v2.5.. Makefile # commits since v2.5 which modify
+ # Makefile
+-------------------------------------
+
+You can also give git log a "range" of commits where the first is not
+necessarily an ancestor of the second; for example, if the tips of
+the branches "stable-release" and "master" diverged from a common
+commit some time ago, then
+
+-------------------------------------
+$ git log stable..experimental
+-------------------------------------
+
+will list commits made in the experimental branch but not in the
+stable branch, while
+
+-------------------------------------
+$ git log experimental..stable
+-------------------------------------
+
+will show the list of commits made on the stable branch but not
+the experimental branch.
+
+The "git log" command has a weakness: it must present commits in a
+list. When the history has lines of development that diverged and
+then merged back together, the order in which "git log" presents
+those commits is meaningless.
+
+Most projects with multiple contributors (such as the linux kernel,
+or git itself) have frequent merges, and gitk does a better job of
+visualizing their history. For example,
+
+-------------------------------------
+$ gitk --since="2 weeks ago" drivers/
+-------------------------------------
+
+allows you to browse any commits from the last 2 weeks of commits
+that modified files under the "drivers" directory. (Note: you can
+adjust gitk's fonts by holding down the control key while pressing
+"-" or "+".)
+
+Finally, most commands that take filenames will optionally allow you
+to precede any filename by a commit, to specify a particular version
+of the file:
+
+-------------------------------------
+$ git diff v2.5:Makefile HEAD:Makefile.in
+-------------------------------------
+
+You can also use "git show" to see any such file:
+
+-------------------------------------
+$ git show v2.5:Makefile
+-------------------------------------
+
+Next Steps
+----------
+
+This tutorial should be enough to perform basic distributed revision
+control for your projects. However, to fully understand the depth
+and power of git you need to understand two simple ideas on which it
+is based:
+
+ * The object database is the rather elegant system used to
+ store the history of your project--files, directories, and
+ commits.
+
+ * The index file is a cache of the state of a directory tree,
+ used to create commits, check out working directories, and
+ hold the various trees involved in a merge.
+
+linkgit:gittutorial-2[7][Part two of this tutorial] explains the object
+database, the index file, and a few other odds and ends that you'll
+need to make the most of git.
+
+If you don't want to continue with that right away, a few other
+digressions that may be interesting at this point are:
+
+ * linkgit:git-format-patch[1], linkgit:git-am[1]: These convert
+ series of git commits into emailed patches, and vice versa,
+ useful for projects such as the linux kernel which rely heavily
+ on emailed patches.
+
+ * linkgit:git-bisect[1]: When there is a regression in your
+ project, one way to track down the bug is by searching through
+ the history to find the exact commit that's to blame. Git bisect
+ can help you perform a binary search for that commit. It is
+ smart enough to perform a close-to-optimal search even in the
+ case of complex non-linear history with lots of merged branches.

-A tutorial introduction to git: part two
-========================================
-
-You should work through link:tutorial.html[A tutorial introduction to
-git] before reading this tutorial.
-
-The goal of this tutorial is to introduce two fundamental pieces of
-git's architecture--the object database and the index file--and to
-provide the reader with everything necessary to understand the rest
-of the git documentation.
-
-The git object database
------------------------
-
-Let's start a new project and create a small amount of history:
-
-------------------------------------------------
-$ mkdir test-project
-$ cd test-project
-$ git init
-Initialized empty Git repository in .git/
-$ echo 'hello world' > file.txt
-$ git add .
-$ git commit -a -m "initial commit"
-Created initial commit 54196cc2703dc165cbd373a65a4dcf22d50ae7f7
- create mode 100644 file.txt
-$ echo 'hello world!' >file.txt
-$ git commit -a -m "add emphasis"
-Created commit c4d59f390b9cfd4318117afde11d601c1085f241
-------------------------------------------------
-
-What are the 40 digits of hex that git responded to the commit with?
-
-We saw in part one of the tutorial that commits have names like this.
-It turns out that every object in the git history is stored under
-such a 40-digit hex name. That name is the SHA1 hash of the object's
-contents; among other things, this ensures that git will never store
-the same data twice (since identical data is given an identical SHA1
-name), and that the contents of a git object will never change (since
-that would change the object's name as well).
-
-It is expected that the content of the commit object you created while
-following the example above generates a different SHA1 hash than
-the one shown above because the commit object records the time when
-it was created and the name of the person performing the commit.
-
-We can ask git about this particular object with the cat-file
-command. Don't copy the 40 hex digits from this example but use those
-from your own version. Note that you can shorten it to only a few
-characters to save yourself typing all 40 hex digits:
-
-------------------------------------------------
-$ git-cat-file -t 54196cc2
-commit
-$ git-cat-file commit 54196cc2
-tree 92b8b694ffb1675e5975148e1121810081dbdffe
-author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-
-initial commit
-------------------------------------------------
-
-A tree can refer to one or more "blob" objects, each corresponding to
-a file. In addition, a tree can also refer to other tree objects,
-thus creating a directory hierarchy. You can examine the contents of
-any tree using ls-tree (remember that a long enough initial portion
-of the SHA1 will also work):
-
-------------------------------------------------
-$ git ls-tree 92b8b694
-100644 blob 3b18e512dba79e4c8300dd08aeb37f8e728b8dad file.txt
-------------------------------------------------
-
-Thus we see that this tree has one file in it. The SHA1 hash is a
-reference to that file's data:
-
-------------------------------------------------
-$ git cat-file -t 3b18e512
-blob
-------------------------------------------------
-
-A "blob" is just file data, which we can also examine with cat-file:
-
-------------------------------------------------
-$ git cat-file blob 3b18e512
-hello world
-------------------------------------------------
-
-Note that this is the old file data; so the object that git named in
-its response to the initial tree was a tree with a snapshot of the
-directory state that was recorded by the first commit.
-
-All of these objects are stored under their SHA1 names inside the git
-directory:
-
-------------------------------------------------
-$ find .git/objects/
-.git/objects/
-.git/objects/pack
-.git/objects/info
-.git/objects/3b
-.git/objects/3b/18e512dba79e4c8300dd08aeb37f8e728b8dad
-.git/objects/92
-.git/objects/92/b8b694ffb1675e5975148e1121810081dbdffe
-.git/objects/54
-.git/objects/54/196cc2703dc165cbd373a65a4dcf22d50ae7f7
-.git/objects/a0
-.git/objects/a0/423896973644771497bdc03eb99d5281615b51
-.git/objects/d0
-.git/objects/d0/492b368b66bdabf2ac1fd8c92b39d3db916e59
-.git/objects/c4
-.git/objects/c4/d59f390b9cfd4318117afde11d601c1085f241
-------------------------------------------------
-
-and the contents of these files is just the compressed data plus a
-header identifying their length and their type. The type is either a
-blob, a tree, a commit, or a tag.
-
-The simplest commit to find is the HEAD commit, which we can find
-from .git/HEAD:
-
-------------------------------------------------
-$ cat .git/HEAD
-ref: refs/heads/master
-------------------------------------------------
-
-As you can see, this tells us which branch we're currently on, and it
-tells us this by naming a file under the .git directory, which itself
-contains a SHA1 name referring to a commit object, which we can
-examine with cat-file:
-
-------------------------------------------------
-$ cat .git/refs/heads/master
-c4d59f390b9cfd4318117afde11d601c1085f241
-$ git cat-file -t c4d59f39
-commit
-$ git cat-file commit c4d59f39
-tree d0492b368b66bdabf2ac1fd8c92b39d3db916e59

-committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143418702 -0500
-
-add emphasis
-------------------------------------------------
-
-The "tree" object here refers to the new state of the tree:
-
-------------------------------------------------
-$ git ls-tree d0492b36
-100644 blob a0423896973644771497bdc03eb99d5281615b51 file.txt
-$ git cat-file blob a0423896
-hello world!
-------------------------------------------------
-
-and the "parent" object refers to the previous commit:
-
-------------------------------------------------
-$ git-cat-file commit 54196cc2
-tree 92b8b694ffb1675e5975148e1121810081dbdffe
-author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-
-initial commit
-------------------------------------------------
-
-The tree object is the tree we examined first, and this commit is
-unusual in that it lacks any parent.
-
-Most commits have only one parent, but it is also common for a commit
-to have multiple parents. In that case the commit represents a
-merge, with the parent references pointing to the heads of the merged
-branches.
-
-Besides blobs, trees, and commits, the only remaining type of object
-is a "tag", which we won't discuss here; refer to linkgit:git-tag[1]
-for details.
-
-So now we know how git uses the object database to represent a
-project's history:
-
- * "commit" objects refer to "tree" objects representing the
- snapshot of a directory tree at a particular point in the
- history, and refer to "parent" commits to show how they're
- connected into the project history.
- * "tree" objects represent the state of a single directory,
- associating directory names to "blob" objects containing file
- data and "tree" objects containing subdirectory information.
- * "blob" objects contain file data without any other structure.
- * References to commit objects at the head of each branch are
- stored in files under .git/refs/heads/.
- * The name of the current branch is stored in .git/HEAD.
-
-Note, by the way, that lots of commands take a tree as an argument.
-But as we can see above, a tree can be referred to in many different
-ways--by the SHA1 name for that tree, by the name of a commit that
-refers to the tree, by the name of a branch whose head refers to that
-tree, etc.--and most such commands can accept any of these names.
-
-In command synopses, the word "tree-ish" is sometimes used to
-designate such an argument.
-
-The index file
---------------
-
-The primary tool we've been using to create commits is "git commit
--a", which creates a commit including every change you've made to
-your working tree. But what if you want to commit changes only to
-certain files? Or only certain changes to certain files?
-
-If we look at the way commits are created under the cover, we'll see
-that there are more flexible ways creating commits.
-
-Continuing with our test-project, let's modify file.txt again:
-
-------------------------------------------------
-$ echo "hello world, again" >>file.txt
-------------------------------------------------
-
-but this time instead of immediately making the commit, let's take an
-intermediate step, and ask for diffs along the way to keep track of
-what's happening:
-
-------------------------------------------------
-$ git diff
---- a/file.txt
-+++ b/file.txt
-@@ -1 +1,2 @@
- hello world!
-+hello world, again
-$ git add file.txt
-$ git diff
-------------------------------------------------
-
-The last diff is empty, but no new commits have been made, and the
-head still doesn't contain the new line:
-
-------------------------------------------------
-$ git-diff HEAD
-diff --git a/file.txt b/file.txt
-index a042389..513feba 100644
---- a/file.txt
-+++ b/file.txt
-@@ -1 +1,2 @@
- hello world!
-+hello world, again
-------------------------------------------------
-
-So "git diff" is comparing against something other than the head.
-The thing that it's comparing against is actually the index file,
-which is stored in .git/index in a binary format, but whose contents
-we can examine with ls-files:
-
-------------------------------------------------
-$ git ls-files --stage
-100644 513feba2e53ebbd2532419ded848ba19de88ba00 0 file.txt
-$ git cat-file -t 513feba2
-blob
-$ git cat-file blob 513feba2
-hello world!
-hello world, again
-------------------------------------------------
-
-So what our "git add" did was store a new blob and then put
-a reference to it in the index file. If we modify the file again,
-we'll see that the new modifications are reflected in the "git-diff"
-output:
-
-------------------------------------------------
-$ echo 'again?' >>file.txt
-$ git diff
-index 513feba..ba3da7b 100644
---- a/file.txt
-+++ b/file.txt
-@@ -1,2 +1,3 @@
- hello world!
- hello world, again
-+again?
-------------------------------------------------
-
-With the right arguments, git diff can also show us the difference
-between the working directory and the last commit, or between the
-index and the last commit:
-
-------------------------------------------------
-$ git diff HEAD
-diff --git a/file.txt b/file.txt
-index a042389..ba3da7b 100644
---- a/file.txt
-+++ b/file.txt
-@@ -1 +1,3 @@
- hello world!
-+hello world, again
-+again?
-$ git diff --cached
-diff --git a/file.txt b/file.txt
-index a042389..513feba 100644
---- a/file.txt
-+++ b/file.txt
-@@ -1 +1,2 @@
- hello world!
-+hello world, again
-------------------------------------------------
-
-At any time, we can create a new commit using "git commit" (without
-the -a option), and verify that the state committed only includes the
-changes stored in the index file, not the additional change that is
-still only in our working tree:
-
-------------------------------------------------
-$ git commit -m "repeat"
-$ git diff HEAD
-diff --git a/file.txt b/file.txt
-index 513feba..ba3da7b 100644
---- a/file.txt
-+++ b/file.txt
-@@ -1,2 +1,3 @@
- hello world!
- hello world, again
-+again?
-------------------------------------------------
-
-So by default "git commit" uses the index to create the commit, not
-the working tree; the -a option to commit tells it to first update
-the index with all changes in the working tree.
-
-Finally, it's worth looking at the effect of "git add" on the index
-file:
-
-------------------------------------------------
-$ echo "goodbye, world" >closing.txt
-$ git add closing.txt
-------------------------------------------------
-
-The effect of the "git add" was to add one entry to the index file:
-
-------------------------------------------------
-$ git ls-files --stage
-100644 8b9743b20d4b15be3955fc8d5cd2b09cd2336138 0 closing.txt
-100644 513feba2e53ebbd2532419ded848ba19de88ba00 0 file.txt
-------------------------------------------------
-
-And, as you can see with cat-file, this new entry refers to the
-current contents of the file:
-
-------------------------------------------------
-$ git cat-file blob 8b9743b2
-goodbye, world
-------------------------------------------------
-
-The "status" command is a useful way to get a quick summary of the
-situation:
-
-------------------------------------------------
-$ git status
-# On branch master
-# Changes to be committed:
-# (use "git reset HEAD <file>..." to unstage)
-#
-# new file: closing.txt
-#
-# Changed but not updated:
-# (use "git add <file>..." to update what will be committed)
-#
-# modified: file.txt
-#
-------------------------------------------------
-
-Since the current state of closing.txt is cached in the index file,
-it is listed as "Changes to be committed". Since file.txt has
-changes in the working directory that aren't reflected in the index,
-it is marked "changed but not updated". At this point, running "git
-commit" would create a commit that added closing.txt (with its new
-contents), but that didn't modify file.txt.
-
-Also, note that a bare "git diff" shows the changes to file.txt, but
-not the addition of closing.txt, because the version of closing.txt
-in the index file is identical to the one in the working directory.
-
-In addition to being the staging area for new commits, the index file
-is also populated from the object database when checking out a
-branch, and is used to hold the trees involved in a merge operation.
-See the link:core-tutorial.html[core tutorial] and the relevant man
-pages for details.
-
-What next?
-----------
-
-At this point you should know everything necessary to read the man
-pages for any of the git commands; one good place to start would be
-with the commands mentioned in link:everyday.html[Everyday git]. You
-should be able to find any unknown jargon in the
-link:glossary.html[Glossary].
-
-The link:user-manual.html[Git User's Manual] provides a more
-comprehensive introduction to git.
-
-The link:cvs-migration.html[CVS migration] document explains how to
-import a CVS repository into git, and shows how to use git in a
-CVS-like way.
-
-For some interesting examples of git use, see the
-link:howto-index.html[howtos].
-
-For git developers, the link:core-tutorial.html[Core tutorial] goes
-into detail on the lower-level git mechanisms involved in, for
-example, creating a new commit.

-A tutorial introduction to git (for version 1.5.1 or newer)
-===========================================================
-
-This tutorial explains how to import a new project into git, make
-changes to it, and share changes with other developers.
-
-If you are instead primarily interested in using git to fetch a project,
-for example, to test the latest version, you may prefer to start with
-the first two chapters of link:user-manual.html[The Git User's Manual].
-
-First, note that you can get documentation for a command such as "git
-diff" with:
-
-------------------------------------------------
-$ man git-diff
-------------------------------------------------
-
-It is a good idea to introduce yourself to git with your name and
-public email address before doing any operation. The easiest
-way to do so is:
-
-------------------------------------------------
-$ git config --global user.name "Your Name Comes Here"
-$ git config --global user.email you@yourdomain.example.com
-------------------------------------------------
-
-
-Importing a new project
------------------------
-
-Assume you have a tarball project.tar.gz with your initial work. You
-can place it under git revision control as follows.
-
-------------------------------------------------
-$ tar xzf project.tar.gz
-$ cd project
-$ git init
-------------------------------------------------
-
-Git will reply
-
-------------------------------------------------
-Initialized empty Git repository in .git/
-------------------------------------------------
-
-You've now initialized the working directory--you may notice a new
-directory created, named ".git".
-
-Next, tell git to take a snapshot of the contents of all files under the
-current directory (note the '.'), with linkgit:git-add[1]:
-
-------------------------------------------------
-$ git add .
-------------------------------------------------
-
-This snapshot is now stored in a temporary staging area which git calls
-the "index". You can permanently store the contents of the index in the
-repository with linkgit:git-commit[1]:
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-This will prompt you for a commit message. You've now stored the first
-version of your project in git.
-
-Making changes
---------------
-
-Modify some files, then add their updated contents to the index:
-
-------------------------------------------------
-$ git add file1 file2 file3
-------------------------------------------------
-
-You are now ready to commit. You can see what is about to be committed
-using linkgit:git-diff[1] with the --cached option:
-
-------------------------------------------------
-$ git diff --cached
-------------------------------------------------
-
-(Without --cached, linkgit:git-diff[1] will show you any changes that
-you've made but not yet added to the index.) You can also get a brief
-summary of the situation with linkgit:git-status[1]:
-
-------------------------------------------------
-$ git status
-# On branch master
-# Changes to be committed:
-# (use "git reset HEAD <file>..." to unstage)
-#
-# modified: file1
-# modified: file2
-# modified: file3
-#
-------------------------------------------------
-
-If you need to make any further adjustments, do so now, and then add any
-newly modified content to the index. Finally, commit your changes with:
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-This will again prompt your for a message describing the change, and then
-record a new version of the project.
-
-Alternatively, instead of running `git add` beforehand, you can use
-
-------------------------------------------------
-$ git commit -a
-------------------------------------------------
-
-which will automatically notice any modified (but not new) files, add
-them to the index, and commit, all in one step.
-
-A note on commit messages: Though not required, it's a good idea to
-begin the commit message with a single short (less than 50 character)
-line summarizing the change, followed by a blank line and then a more
-thorough description. Tools that turn commits into email, for
-example, use the first line on the Subject: line and the rest of the
-commit in the body.
-
-Git tracks content not files
-----------------------------
-
-Many revision control systems provide an "add" command that tells the
-system to start tracking changes to a new file. Git's "add" command
-does something simpler and more powerful: `git add` is used both for new
-and newly modified files, and in both cases it takes a snapshot of the
-given files and stages that content in the index, ready for inclusion in
-the next commit.
-
-Viewing project history
------------------------
-
-At any point you can view the history of your changes using
-
-------------------------------------------------
-$ git log
-------------------------------------------------
-
-If you also want to see complete diffs at each step, use
-
-------------------------------------------------
-$ git log -p
-------------------------------------------------
-
-Often the overview of the change is useful to get a feel of
-each step
-
-------------------------------------------------
-$ git log --stat --summary
-------------------------------------------------
-
-Managing branches
------------------
-
-A single git repository can maintain multiple branches of
-development. To create a new branch named "experimental", use
-
-------------------------------------------------
-$ git branch experimental
-------------------------------------------------
-
-If you now run
-
-------------------------------------------------
-$ git branch
-------------------------------------------------
-
-you'll get a list of all existing branches:
-
-------------------------------------------------
- experimental
-* master
-------------------------------------------------
-
-The "experimental" branch is the one you just created, and the
-"master" branch is a default branch that was created for you
-automatically. The asterisk marks the branch you are currently on;

-
-to switch to the experimental branch. Now edit a file, commit the
-change, and switch back to the master branch:
-
-------------------------------------------------
-(edit file)
-$ git commit -a
-$ git checkout master
-------------------------------------------------
-
-Check that the change you made is no longer visible, since it was
-made on the experimental branch and you're back on the master branch.
-
-You can make a different change on the master branch:
-
-------------------------------------------------
-(edit file)
-$ git commit -a
-------------------------------------------------
-
-at this point the two branches have diverged, with different changes
-made in each. To merge the changes made in experimental into master, run
-
-------------------------------------------------
-$ git merge experimental
-------------------------------------------------
-
-If the changes don't conflict, you're done. If there are conflicts,
-markers will be left in the problematic files showing the conflict;
-
-------------------------------------------------
-$ git diff
-------------------------------------------------
-
-will show this. Once you've edited the files to resolve the
-conflicts,
-
-------------------------------------------------
-$ git commit -a
-------------------------------------------------
-
-will commit the result of the merge. Finally,
-
-------------------------------------------------
-$ gitk
-------------------------------------------------
-
-will show a nice graphical representation of the resulting history.
-
-At this point you could delete the experimental branch with
-
-------------------------------------------------
-$ git branch -d experimental
-------------------------------------------------
-
-This command ensures that the changes in the experimental branch are
-already in the current branch.
-
-If you develop on a branch crazy-idea, then regret it, you can always
-delete the branch with
-
--------------------------------------
-$ git branch -D crazy-idea
--------------------------------------
-
-Branches are cheap and easy, so this is a good way to try something
-out.
-
-Using git for collaboration
----------------------------
-
-Suppose that Alice has started a new project with a git repository in
-/home/alice/project, and that Bob, who has a home directory on the
-same machine, wants to contribute.
-
-Bob begins with:
-
-------------------------------------------------
-$ git clone /home/alice/project myrepo
-------------------------------------------------
-
-This creates a new directory "myrepo" containing a clone of Alice's
-repository. The clone is on an equal footing with the original
-project, possessing its own copy of the original project's history.
-
-Bob then makes some changes and commits them:
-
-------------------------------------------------
-(edit files)
-$ git commit -a
-(repeat as necessary)
-------------------------------------------------
-
-When he's ready, he tells Alice to pull changes from the repository
-at /home/bob/myrepo. She does this with:
-
-------------------------------------------------
-$ cd /home/alice/project
-$ git pull /home/bob/myrepo master
-------------------------------------------------
-
-This merges the changes from Bob's "master" branch into Alice's
-current branch. If Alice has made her own changes in the meantime,
-then she may need to manually fix any conflicts. (Note that the
-"master" argument in the above command is actually unnecessary, as it
-is the default.)
-
-The "pull" command thus performs two operations: it fetches changes
-from a remote branch, then merges them into the current branch.
-
-When you are working in a small closely knit group, it is not
-unusual to interact with the same repository over and over
-again. By defining 'remote' repository shorthand, you can make
-it easier:
-
-------------------------------------------------
-$ git remote add bob /home/bob/myrepo
-------------------------------------------------
-
-With this, Alice can perform the first operation alone using the
-"git fetch" command without merging them with her own branch,
-using:
-
--------------------------------------
-$ git fetch bob
--------------------------------------
-
-Unlike the longhand form, when Alice fetches from Bob using a
-remote repository shorthand set up with `git remote`, what was
-fetched is stored in a remote tracking branch, in this case
-`bob/master`. So after this:
-
--------------------------------------
-$ git log -p master..bob/master
--------------------------------------
-
-shows a list of all the changes that Bob made since he branched from
-Alice's master branch.
-
-After examining those changes, Alice
-could merge the changes into her master branch:
-
--------------------------------------
-$ git merge bob/master
--------------------------------------
-
-This `merge` can also be done by 'pulling from her own remote
-tracking branch', like this:
-
--------------------------------------
-$ git pull . remotes/bob/master
--------------------------------------
-
-Note that git pull always merges into the current branch,
-regardless of what else is given on the command line.
-
-Later, Bob can update his repo with Alice's latest changes using
-
--------------------------------------
-$ git pull
--------------------------------------
-
-Note that he doesn't need to give the path to Alice's repository;
-when Bob cloned Alice's repository, git stored the location of her
-repository in the repository configuration, and that location is
-used for pulls:
-
--------------------------------------
-$ git config --get remote.origin.url
-/home/alice/project
--------------------------------------
-
-(The complete configuration created by git-clone is visible using
-"git config -l", and the linkgit:git-config[1] man page
-explains the meaning of each option.)
-
-Git also keeps a pristine copy of Alice's master branch under the
-name "origin/master":
-
--------------------------------------
-$ git branch -r
- origin/master
--------------------------------------
-
-If Bob later decides to work from a different host, he can still
-perform clones and pulls using the ssh protocol:
-
--------------------------------------
-$ git clone alice.org:/home/alice/project myrepo
--------------------------------------
-
-Alternatively, git has a native protocol, or can use rsync or http;
-see linkgit:git-pull[1] for details.
-
-Git can also be used in a CVS-like mode, with a central repository
-that various users push changes to; see linkgit:git-push[1] and
-link:cvs-migration.html[git for CVS users].
-
-Exploring history
------------------
-
-Git history is represented as a series of interrelated commits. We
-have already seen that the git log command can list those commits.
-Note that first line of each git log entry also gives a name for the
-commit:
-
--------------------------------------
-$ git log
-commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
-Author: Junio C Hamano <junkio@cox.net>
-Date: Tue May 16 17:18:22 2006 -0700
-
- merge-base: Clarify the comments on post processing.
--------------------------------------
-
-We can give this name to git show to see the details about this
-commit.
-
--------------------------------------
-$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
--------------------------------------
-
-But there are other ways to refer to commits. You can use any initial
-part of the name that is long enough to uniquely identify the commit:
-
--------------------------------------
-$ git show c82a22c39c # the first few characters of the name are
- # usually enough
-$ git show HEAD # the tip of the current branch
-$ git show experimental # the tip of the "experimental" branch
--------------------------------------
-
-Every commit usually has one "parent" commit
-which points to the previous state of the project:
-
--------------------------------------
-$ git show HEAD^ # to see the parent of HEAD
-$ git show HEAD^^ # to see the grandparent of HEAD
-$ git show HEAD~4 # to see the great-great grandparent of HEAD
--------------------------------------
-
-Note that merge commits may have more than one parent:
-
--------------------------------------
-$ git show HEAD^1 # show the first parent of HEAD (same as HEAD^)
-$ git show HEAD^2 # show the second parent of HEAD
--------------------------------------
-
-You can also give commits names of your own; after running
-
--------------------------------------
-$ git-tag v2.5 1b2e1d63ff
--------------------------------------
-
-you can refer to 1b2e1d63ff by the name "v2.5". If you intend to
-share this name with other people (for example, to identify a release
-version), you should create a "tag" object, and perhaps sign it; see
-linkgit:git-tag[1] for details.
-
-Any git command that needs to know a commit can take any of these
-names. For example:
-
--------------------------------------
-$ git diff v2.5 HEAD # compare the current HEAD to v2.5
-$ git branch stable v2.5 # start a new branch named "stable" based
- # at v2.5
-$ git reset --hard HEAD^ # reset your current branch and working
- # directory to its state at HEAD^
--------------------------------------
-
-Be careful with that last command: in addition to losing any changes
-in the working directory, it will also remove all later commits from
-this branch. If this branch is the only branch containing those
-commits, they will be lost. Also, don't use "git reset" on a
-publicly-visible branch that other developers pull from, as it will
-force needless merges on other developers to clean up the history.
-If you need to undo changes that you have pushed, use linkgit:git-revert[1]
-instead.
-
-The git grep command can search for strings in any version of your
-project, so
-
--------------------------------------
-$ git grep "hello" v2.5
--------------------------------------
-
-searches for all occurrences of "hello" in v2.5.
-
-If you leave out the commit name, git grep will search any of the
-files it manages in your current directory. So
-
--------------------------------------
-$ git grep "hello"
--------------------------------------
-
-is a quick way to search just the files that are tracked by git.
-
-Many git commands also take sets of commits, which can be specified
-in a number of ways. Here are some examples with git log:
-
--------------------------------------
-$ git log v2.5..v2.6 # commits between v2.5 and v2.6
-$ git log v2.5.. # commits since v2.5
-$ git log --since="2 weeks ago" # commits from the last 2 weeks
-$ git log v2.5.. Makefile # commits since v2.5 which modify
- # Makefile
--------------------------------------
-
-You can also give git log a "range" of commits where the first is not
-necessarily an ancestor of the second; for example, if the tips of
-the branches "stable-release" and "master" diverged from a common
-commit some time ago, then
-
--------------------------------------
-$ git log stable..experimental
--------------------------------------
-
-will list commits made in the experimental branch but not in the
-stable branch, while
-
--------------------------------------
-$ git log experimental..stable
--------------------------------------
-
-will show the list of commits made on the stable branch but not
-the experimental branch.
-
-The "git log" command has a weakness: it must present commits in a
-list. When the history has lines of development that diverged and
-then merged back together, the order in which "git log" presents
-those commits is meaningless.
-
-Most projects with multiple contributors (such as the linux kernel,
-or git itself) have frequent merges, and gitk does a better job of
-visualizing their history. For example,
-
--------------------------------------
-$ gitk --since="2 weeks ago" drivers/
--------------------------------------
-
-allows you to browse any commits from the last 2 weeks of commits
-that modified files under the "drivers" directory. (Note: you can
-adjust gitk's fonts by holding down the control key while pressing
-"-" or "+".)
-
-Finally, most commands that take filenames will optionally allow you
-to precede any filename by a commit, to specify a particular version
-of the file:
-
--------------------------------------
-$ git diff v2.5:Makefile HEAD:Makefile.in
--------------------------------------
-
-You can also use "git show" to see any such file:
-
--------------------------------------
-$ git show v2.5:Makefile
--------------------------------------
-
-Next Steps
-----------
-
-This tutorial should be enough to perform basic distributed revision
-control for your projects. However, to fully understand the depth
-and power of git you need to understand two simple ideas on which it
-is based:
-
- * The object database is the rather elegant system used to
- store the history of your project--files, directories, and
- commits.
-
- * The index file is a cache of the state of a directory tree,
- used to create commits, check out working directories, and
- hold the various trees involved in a merge.
-
-link:tutorial-2.html[Part two of this tutorial] explains the object
-database, the index file, and a few other odds and ends that you'll
-need to make the most of git.
-
-If you don't want to continue with that right away, a few other
-digressions that may be interesting at this point are:
-
- * linkgit:git-format-patch[1], linkgit:git-am[1]: These convert
- series of git commits into emailed patches, and vice versa,
- useful for projects such as the linux kernel which rely heavily
- on emailed patches.
-
- * linkgit:git-bisect[1]: When there is a regression in your
- project, one way to track down the bug is by searching through
- the history to find the exact commit that's to blame. Git bisect
- can help you perform a binary search for that commit. It is
- smart enough to perform a close-to-optimal search even in the
- case of complex non-linear history with lots of merged branches.
-
- * link:everyday.html[Everyday GIT with 20 Commands Or So]
-
- * link:cvs-migration.html[git for CVS users].
solution is to retry the push after first updating your work by either a
pull or a fetch followed by a rebase; see the
<<setting-up-a-shared-repository,next section>> and

Setting up a shared repository
Another way to collaborate is by using a model similar to that
commonly used in CVS, where several developers with special rights
all push to and pull from a single shared repository. See
-link:cvs-migration.html[git for CVS users] for instructions on how to
