Ok, so you're a CVS user. That's ok, it's a treatable condition, and the
first step to recovery is admitting you have a problem. The fact that
already.
The thing about CVS is that it absolutely sucks as a source control

however, may be a bit 'too' different (read: "good") for your taste, and
does a lot of things differently.

tracking 'project' history. This sometimes causes problems if you are
used to doing very strange things in CVS, in particular if you're doing

+things like making branches of just a subset of the project. git can't
track that, since git never tracks things on the level of an individual
file, only on the whole project level.
people think it's a bug in CVS that makes it tag (and check in changes)
one file at a time. So most projects you'll ever see will use CVS
'as if' it was sane. In which case you'll find it very easy indeed to

First off: this is not a git tutorial. See

that you're actually working in (your working directory, or your
-"checked out tree"). Git does not have that notion at all, and all git

working directories 'are' the repositories. However, you can easily

Don't worry about the fact that the file that the `HEAD` link points to
doesn't even exist yet -- you haven't created the commit that will
git-cat-file -t 557db03de997c86a4a028e1ebd3a1ceb225be238

on its standard input, and it will write out the resulting object name for the

Copying repositories
--------------------
-Git repositories are normally totally self-sufficient, and it's worth noting
+git repositories are normally totally self-sufficient, and it's worth noting
that unlike CVS, for example, there is no separate notion of
"repository" and "working tree". A git repository normally *is* the
working tree, with the local git information hidden in the `.git`
just telling `git checkout` what the base of the checkout would be.
In other words, if you have an earlier tag or branch, you'd just do
- git checkout -b mybranch earlier-commit
+------------
+git checkout -b mybranch earlier-commit
+------------
and it would create the new branch `mybranch` at the earlier commit,
and check out the state at that time.
You can always just jump back to your original `master` branch by doing
- git checkout master
+------------
+git checkout master
+------------
(or any other branch-name, for that matter) and if you forget which
branch you happen to be on, a simple
- ls -l .git/HEAD
+------------
+ls -l .git/HEAD
+------------
-will tell you where it's pointing. To get the list of branches
-you have, you can say
+will tell you where it's pointing (Note that on platforms with bad or no
+symlink support, you have to execute
- git branch
+------------
+cat .git/HEAD
+------------
+
+instead). To get the list of branches you have, you can say
+
+------------
+git branch
+------------
which is nothing more than a simple script around `ls .git/refs/heads`.
There will be asterisk in front of the branch you are currently on.
Sometimes you may wish to create a new branch _without_ actually
checking it out and switching to it. If so, just use the command
- git branch <branchname> [startingpoint]
+------------
+git branch <branchname> [startingpoint]
+------------
which will simply _create_ the branch, but will not do anything further.
You can then later -- once you decide that you want to actually develop
! [mybranch] Some work.
--

-+ [master~1] Some fun.
++ [mybranch] Some work.

to the `master` branch. Let's go back to `mybranch`, and run
resolve to get the "upstream changes" back to your branch.
- git checkout mybranch
- git resolve HEAD master "Merge upstream changes."
+------------
+git checkout mybranch
+git resolve HEAD master "Merge upstream changes."

This outputs something like this (the actual commit object names
would be different)

the remote machine via `ssh`.

Once you fetch from the remote repository, you `resolve` that

the network internally uses an SSH connection.
-Your private repository's GIT directory is usually `.git`, but
+Your private repository's git directory is usually `.git`, but
your public repository is often named after the project name,
i.e. `<project>.git`. Let's create such a public repository for
project `my-git`. After logging into the remote machine, create
an empty directory:
- mkdir my-git.git
+------------
+mkdir my-git.git
+------------
-Then, make that directory into a GIT repository by running
+Then, make that directory into a git repository by running
`git init-db`, but this time, since its name is not the usual
`.git`, we do things slightly differently:
- GIT_DIR=my-git.git git-init-db
+------------
+GIT_DIR=my-git.git git-init-db
+------------
Make sure this directory is available for others you want your
changes to be pulled by via the transport of your choice. Also
Come back to the machine you have your private repository. From
there, run this command:
- git push <public-host>:/path/to/my-git.git master
+------------
+git push <public-host>:/path/to/my-git.git master
+------------
This synchronizes your public repository to match the named
branch head (i.e. `master` in this case) and objects reachable
repository. Kernel.org mirror network takes care of the
propagation to other publicly visible machines:
- git push master.kernel.org:/pub/scm/git/git.git/
+------------
+git push master.kernel.org:/pub/scm/git/git.git/
+------------
Packing your repository
immutable once they are created, there is a way to optimize the
storage by "packing them together". The command
- git repack
+------------
+git repack
+------------
will do it for you. If you followed the tutorial examples, you
would have accumulated about 17 objects in `.git/objects/??/`
Once you have packed objects, you do not need to leave the
unpacked objects that are contained in the pack file anymore.

+ 1.txt - a file

+Test the handling of mulitple directories which have matching file
