-Everyday Git With 20 Commands Or So
-===================================
-
-<<Individual Developer (Standalone)>> commands are essential for
-anybody who makes a commit, even for somebody who works alone.
-
-If you work with other people, you will need commands listed in
-the <<Individual Developer (Participant)>> section as well.
-
-People who play the <<Integrator>> role need to learn some more
-commands in addition to the above.
-
-<<Repository Administration>> commands are for system
-administrators who are responsible for the care and feeding
-of Git repositories.
-
-
-Individual Developer (Standalone)[[Individual Developer (Standalone)]]
-----------------------------------------------------------------------
-
-A standalone individual developer does not exchange patches with
-other people, and works alone in a single repository, using the
-following commands.
-
- * linkgit:git-init[1] to create a new repository.
-
- * linkgit:git-show-branch[1] to see where you are.
-
- * linkgit:git-log[1] to see what happened.
-
- * linkgit:git-checkout[1] and linkgit:git-branch[1] to switch
- branches.
-
- * linkgit:git-add[1] to manage the index file.
-
- * linkgit:git-diff[1] and linkgit:git-status[1] to see what
- you are in the middle of doing.
-
- * linkgit:git-commit[1] to advance the current branch.
-
- * linkgit:git-reset[1] and linkgit:git-checkout[1] (with
- pathname parameters) to undo changes.
-
- * linkgit:git-merge[1] to merge between local branches.
-
- * linkgit:git-rebase[1] to maintain topic branches.
-
- * linkgit:git-tag[1] to mark known point.
-
-Examples
-~~~~~~~~
-
-Use a tarball as a starting point for a new repository.::
-+
-------------
-$ tar zxf frotz.tar.gz
-$ cd frotz
-$ git init
-$ git add . <1>
-$ git commit -m "import of frotz source tree."
-$ git tag v2.43 <2>
-------------
-+
-<1> add everything under the current directory.
-<2> make a lightweight, unannotated tag.
-
-Create a topic branch and develop.::
-+
-------------
-$ git checkout -b alsa-audio <1>
-$ edit/compile/test
-$ git checkout -- curses/ux_audio_oss.c <2>
-$ git add curses/ux_audio_alsa.c <3>
-$ edit/compile/test
-$ git diff HEAD <4>
-$ git commit -a -s <5>
-$ edit/compile/test
-$ git reset --soft HEAD^ <6>
-$ edit/compile/test
-$ git diff ORIG_HEAD <7>
-$ git commit -a -c ORIG_HEAD <8>
-$ git checkout master <9>
-$ git merge alsa-audio <10>
-$ git log --since='3 days ago' <11>
-$ git log v2.43.. curses/ <12>
-------------
-+
-<1> create a new topic branch.
-<2> revert your botched changes in `curses/ux_audio_oss.c`.
-<3> you need to tell Git if you added a new file; removal and
-modification will be caught if you do `git commit -a` later.
-<4> to see what changes you are committing.
-<5> commit everything as you have tested, with your sign-off.
-<6> take the last commit back, keeping what is in the working tree.
-<7> look at the changes since the premature commit we took back.
-<8> redo the commit undone in the previous step, using the message
-you originally wrote.
-<9> switch to the master branch.
-<10> merge a topic branch into your master branch.
-<11> review commit logs; other forms to limit output can be
-combined and include `--max-count=10` (show 10 commits),
-`--until=2005-12-10`, etc.
-<12> view only the changes that touch what's in `curses/`
-directory, since `v2.43` tag.
-
-
-Individual Developer (Participant)[[Individual Developer (Participant)]]
-------------------------------------------------------------------------
-
-A developer working as a participant in a group project needs to
-learn how to communicate with others, and uses these commands in
-addition to the ones needed by a standalone developer.
-
- * linkgit:git-clone[1] from the upstream to prime your local
- repository.
-
- * linkgit:git-pull[1] and linkgit:git-fetch[1] from "origin"
- to keep up-to-date with the upstream.
-
- * linkgit:git-push[1] to shared repository, if you adopt CVS
- style shared repository workflow.
-
- * linkgit:git-format-patch[1] to prepare e-mail submission, if
- you adopt Linux kernel-style public forum workflow.
-
-Examples
-~~~~~~~~
-
-Clone the upstream and work on it. Feed changes to upstream.::
-+
-------------
-$ git clone git://git.kernel.org/pub/scm/.../torvalds/linux-2.6 my2.6
-$ cd my2.6
-$ edit/compile/test; git commit -a -s <1>
-$ git format-patch origin <2>
-$ git pull <3>
-$ git log -p ORIG_HEAD.. arch/i386 include/asm-i386 <4>
-$ git pull git://git.kernel.org/pub/.../jgarzik/libata-dev.git ALL <5>
-$ git reset --hard ORIG_HEAD <6>
-$ git gc <7>
-$ git fetch --tags <8>
-------------
-+
-<1> repeat as needed.
-<2> extract patches from your branch for e-mail submission.
-<3> `git pull` fetches from `origin` by default and merges into the
-current branch.
-<4> immediately after pulling, look at the changes done upstream
-since last time we checked, only in the
-area we are interested in.
-<5> fetch from a specific branch from a specific repository and merge.
-<6> revert the pull.
-<7> garbage collect leftover objects from reverted pull.
-<8> from time to time, obtain official tags from the `origin`
-and store them under `.git/refs/tags/`.
-
-
-Push into another repository.::
-+
-------------
-satellite$ git clone mothership:frotz frotz <1>
-satellite$ cd frotz
-satellite$ git config --get-regexp '^(remote|branch)\.' <2>
-remote.origin.url mothership:frotz
-remote.origin.fetch refs/heads/*:refs/remotes/origin/*
-branch.master.remote origin
-branch.master.merge refs/heads/master
-satellite$ git config remote.origin.push \
- master:refs/remotes/satellite/master <3>
-satellite$ edit/compile/test/commit
-satellite$ git push origin <4>
-
-mothership$ cd frotz
-mothership$ git checkout master
-mothership$ git merge satellite/master <5>
-------------
-+
-<1> mothership machine has a frotz repository under your home
-directory; clone from it to start a repository on the satellite
-machine.
-<2> clone sets these configuration variables by default.
-It arranges `git pull` to fetch and store the branches of mothership
-machine to local `remotes/origin/*` remote-tracking branches.
-<3> arrange `git push` to push local `master` branch to
-`remotes/satellite/master` branch of the mothership machine.
-<4> push will stash our work away on `remotes/satellite/master`
-remote-tracking branch on the mothership machine. You could use this
-as a back-up method.
-<5> on mothership machine, merge the work done on the satellite
-machine into the master branch.
-
-Branch off of a specific tag.::
-+
-------------
-$ git checkout -b private2.6.14 v2.6.14 <1>
-$ edit/compile/test; git commit -a
-$ git checkout master
-$ git format-patch -k -m --stdout v2.6.14..private2.6.14 |
- git am -3 -k <2>
-------------
-+
-<1> create a private branch based on a well known (but somewhat behind)
-tag.
-<2> forward port all changes in `private2.6.14` branch to `master` branch
-without a formal "merging".
-
-
-Integrator[[Integrator]]
-------------------------
-
-A fairly central person acting as the integrator in a group
-project receives changes made by others, reviews and integrates
-them and publishes the result for others to use, using these
-commands in addition to the ones needed by participants.
-
- * linkgit:git-am[1] to apply patches e-mailed in from your
- contributors.
-
- * linkgit:git-pull[1] to merge from your trusted lieutenants.
-
- * linkgit:git-format-patch[1] to prepare and send suggested
- alternative to contributors.
-
- * linkgit:git-revert[1] to undo botched commits.
-
- * linkgit:git-push[1] to publish the bleeding edge.
-
-
-Examples
-~~~~~~~~
-
-My typical Git day.::
-+
-------------
-$ git status <1>
-$ git show-branch <2>
-$ mailx <3>
-& s 2 3 4 5 ./+to-apply
-& s 7 8 ./+hold-linus
-& q
-$ git checkout -b topic/one master
-$ git am -3 -i -s -u ./+to-apply <4>
-$ compile/test
-$ git checkout -b hold/linus && git am -3 -i -s -u ./+hold-linus <5>

-$ compile/test
-$ git tag -s -m "GIT 0.99.9x" v0.99.9x <10>
-$ git fetch ko && git show-branch master maint 'tags/ko-*' <11>
-$ git push ko <12>
-$ git push ko v0.99.9x <13>
-------------
-+
-<1> see what I was in the middle of doing, if any.
-<2> see what topic branches I have and think about how ready
-they are.
-<3> read mails, save ones that are applicable, and save others
-that are not quite ready.
-<4> apply them, interactively, with my sign-offs.
-<5> create topic branch as needed and apply, again with my
-sign-offs.
-<6> rebase internal topic branch that has not been merged to the
-master or exposed as a part of a stable branch.
-<7> restart `pu` every time from the next.
-<8> and bundle topic branches still cooking.
-<9> backport a critical fix.
-<10> create a signed tag.
-<11> make sure I did not accidentally rewind master beyond what I
-already pushed out. `ko` shorthand points at the repository I have
-at kernel.org, and looks like this:
-+
-------------
-$ cat .git/remotes/ko
-URL: kernel.org:/pub/scm/git/git.git
-Pull: master:refs/tags/ko-master
-Pull: next:refs/tags/ko-next
-Pull: maint:refs/tags/ko-maint
-Push: master
-Push: next
-Push: +pu
-Push: maint
-------------
-+
-In the output from `git show-branch`, `master` should have
-everything `ko-master` has, and `next` should have
-everything `ko-next` has.
-
-<12> push out the bleeding edge.
-<13> push the tag out, too.
-
-
-Repository Administration[[Repository Administration]]
-------------------------------------------------------
-
-A repository administrator uses the following tools to set up
-and maintain access to the repository by developers.
-
- * linkgit:git-daemon[1] to allow anonymous download from
- repository.
-
- * linkgit:git-shell[1] can be used as a 'restricted login shell'
- for shared central repository users.
-
-link:howto/update-hook-example.html[update hook howto] has a good
-example of managing a shared central repository.
-
-
-Examples
-~~~~~~~~
-We assume the following in /etc/services::
-+
-------------
-$ grep 9418 /etc/services
-git 9418/tcp # Git Version Control System
-------------
-
-Run git-daemon to serve /pub/scm from inetd.::
-+
-------------
-$ grep git /etc/inetd.conf
-git stream tcp nowait nobody \
- /usr/bin/git-daemon git-daemon --inetd --export-all /pub/scm
-------------
-+
-The actual configuration line should be on one line.
-
-Run git-daemon to serve /pub/scm from xinetd.::
-+
-------------
-$ cat /etc/xinetd.d/git-daemon
-# default: off
-# description: The Git server offers access to Git repositories

- wait = no
- user = nobody
- server = /usr/bin/git-daemon
- server_args = --inetd --export-all --base-path=/pub/scm
- log_on_failure += USERID

+=========================
+
+NAME
+----
+git-interpret-trailers - help add stuctured information into commit messages
+
+SYNOPSIS
+--------
+[verse]
+'git interpret-trailers' [--trim-empty] [(--trailer <token>[(=|:)<value>])...] [<file>...]
+
+DESCRIPTION
+-----------
+Help adding 'trailers' lines, that look similar to RFC 822 e-mail
+headers, at the end of the otherwise free-form part of a commit
+message.
+
+This command reads some patches or commit messages from either the
+<file> arguments or the standard input if no <file> is specified. Then
+this command applies the arguments passed using the `--trailer`
+option, if any, to the commit message part of each input file. The
+result is emitted on the standard output.
+
+Some configuration variables control the way the `--trailer` arguments
+are applied to each commit message and the way any existing trailer in
+the commit message is changed. They also make it possible to
+automatically add some trailers.
+
+By default, a '<token>=<value>' or '<token>:<value>' argument given
+using `--trailer` will be appended after the existing trailers only if
+the last trailer has a different (<token>, <value>) pair (or if there
+is no existing trailer). The <token> and <value> parts will be trimmed
+to remove starting and trailing whitespace, and the resulting trimmed
+<token> and <value> will appear in the message like this:
+
+------------------------------------------------
+token: value
+------------------------------------------------
+
+This means that the trimmed <token> and <value> will be separated by
+`': '` (one colon followed by one space).
+
+By default the new trailer will appear at the end of all the existing
+trailers. If there is no existing trailer, the new trailer will appear
+after the commit message part of the ouput, and, if there is no line
+with only spaces at the end of the commit message part, one blank line
+will be added before the new trailer.
+
+Existing trailers are extracted from the input message by looking for
+a group of one or more lines that contain a colon (by default), where
+the group is preceded by one or more empty (or whitespace-only) lines.
+The group must either be at the end of the message or be the last
+non-whitespace lines before a line that starts with '---'. Such three
+minus signs start the patch part of the message.
+
+When reading trailers, there can be whitespaces before and after the
+token, the separator and the value. There can also be whitespaces
+indide the token and the value.
+
+Note that 'trailers' do not follow and are not intended to follow many
+rules for RFC 822 headers. For example they do not follow the line
+folding rules, the encoding rules and probably many other rules.
+
+OPTIONS
+-------
+--trim-empty::
+ If the <value> part of any trailer contains only whitespace,
+ the whole trailer will be removed from the resulting message.
+ This apply to existing trailers as well as new trailers.
+
+--trailer <token>[(=|:)<value>]::
+ Specify a (<token>, <value>) pair that should be applied as a
+ trailer to the input messages. See the description of this
+ command.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+trailer.separators::
+ This option tells which characters are recognized as trailer
+ separators. By default only ':' is recognized as a trailer
+ separator, except that '=' is always accepted on the command
+ line for compatibility with other git commands.
++
+The first character given by this option will be the default character
+used when another separator is not specified in the config for this
+trailer.
++
+For example, if the value for this option is "%=$", then only lines
+using the format '<token><sep><value>' with <sep> containing '%', '='
+or '$' and then spaces will be considered trailers. And '%' will be
+the default separator used, so by default trailers will appear like:
+'<token>% <value>' (one percent sign and one space will appear between
+the token and the value).
+
+trailer.where::
+ This option tells where a new trailer will be added.
++
+This can be `end`, which is the default, `start`, `after` or `before`.
++
+If it is `end`, then each new trailer will appear at the end of the
+existing trailers.
++
+If it is `start`, then each new trailer will appear at the start,
+instead of the end, of the existing trailers.
++
+If it is `after`, then each new trailer will appear just after the
+last trailer with the same <token>.
++
+If it is `before`, then each new trailer will appear just before the
+first trailer with the same <token>.
+
+trailer.ifexists::
+ This option makes it possible to choose what action will be
+ performed when there is already at least one trailer with the
+ same <token> in the message.
++
+The valid values for this option are: `addIfDifferentNeighbor` (this
+is the default), `addIfDifferent`, `add`, `overwrite` or `doNothing`.
++
+With `addIfDifferentNeighbor`, a new trailer will be added only if no
+trailer with the same (<token>, <value>) pair is above or below the line
+where the new trailer will be added.
++
+With `addIfDifferent`, a new trailer will be added only if no trailer
+with the same (<token>, <value>) pair is already in the message.
++
+With `add`, a new trailer will be added, even if some trailers with
+the same (<token>, <value>) pair are already in the message.
++
+With `replace`, an existing trailer with the same <token> will be
+deleted and the new trailer will be added. The deleted trailer will be
+the closest one (with the same <token>) to the place where the new one
+will be added.
++
+With `doNothing`, nothing will be done; that is no new trailer will be
+added if there is already one with the same <token> in the message.
+
+trailer.ifmissing::
+ This option makes it possible to choose what action will be
+ performed when there is not yet any trailer with the same
+ <token> in the message.
++
+The valid values for this option are: `add` (this is the default) and
+`doNothing`.
++
+With `add`, a new trailer will be added.
++
+With `doNothing`, nothing will be done.
+
+trailer.<token>.key::
+ This `key` will be used instead of <token> in the trailer. At
+ the end of this key, a separator can appear and then some
+ space characters. By default the only valid separator is ':',
+ but this can be changed using the `trailer.separators` config
+ variable.
++
+If there is a separator, then the key will be used instead of both the
+<token> and the default separator when adding the trailer.
+
+trailer.<token>.where::
+ This option takes the same values as the 'trailer.where'
+ configuration variable and it overrides what is specified by
+ that option for trailers with the specified <token>.
+
+trailer.<token>.ifexist::
+ This option takes the same values as the 'trailer.ifexist'
+ configuration variable and it overrides what is specified by
+ that option for trailers with the specified <token>.
+
+trailer.<token>.ifmissing::
+ This option takes the same values as the 'trailer.ifmissing'
+ configuration variable and it overrides what is specified by
+ that option for trailers with the specified <token>.
+
+trailer.<token>.command::
+ This option can be used to specify a shell command that will
+ be called to automatically add or modify a trailer with the
+ specified <token>.
++
+When this option is specified, the behavior is as if a special
+'<token>=<value>' argument were added at the beginning of the command
+line, where <value> is taken to be the standard output of the
+specified command with any leading and trailing whitespace trimmed
+off.
++
+If the command contains the `$ARG` string, this string will be
+replaced with the <value> part of an existing trailer with the same
+<token>, if any, before the command is launched.
++
+If some '<token>=<value>' arguments are also passed on the command
+line, when a 'trailer.<token>.command' is configured, the command will
+also be executed for each of these arguments. And the <value> part of
+these arguments, if any, will be used to replace the `$ARG` string in
+the command.
+
+EXAMPLES
+--------
+
+* Configure a 'sign' trailer with a 'Signed-off-by' key, and then
+ add two of these trailers to a message:
++
+------------
+$ git config trailer.sign.key "Signed-off-by"
+$ cat msg.txt
+subject

+NAME

+giteveryday - A useful minimum set of commands for Everyday Git
+
+SYNOPSIS
+--------
+
+Everyday Git With 20 Commands Or So
+
+DESCRIPTION
+-----------
+
+Git users can broadly be grouped into four categories for the purposes of
+describing here a small set of useful command for everyday Git.
+
+* <<STANDALONE,Individual Developer (Standalone)>> commands are essential
+ for anybody who makes a commit, even for somebody who works alone.
+
+* If you work with other people, you will need commands listed in
+ the <<PARTICIPANT,Individual Developer (Participant)>> section as well.
+
+* People who play the <<INTEGRATOR,Integrator>> role need to learn some
+ more commands in addition to the above.
+
+* <<ADMINISTRATION,Repository Administration>> commands are for system
+ administrators who are responsible for the care and feeding
+ of Git repositories.
+
+
+Individual Developer (Standalone)[[STANDALONE]]
+-----------------------------------------------
+
+A standalone individual developer does not exchange patches with
+other people, and works alone in a single repository, using the
+following commands.
+
+ * linkgit:git-init[1] to create a new repository.
+
+ * linkgit:git-log[1] to see what happened.
+
+ * linkgit:git-checkout[1] and linkgit:git-branch[1] to switch
+ branches.
+
+ * linkgit:git-add[1] to manage the index file.
+
+ * linkgit:git-diff[1] and linkgit:git-status[1] to see what
+ you are in the middle of doing.
+
+ * linkgit:git-commit[1] to advance the current branch.
+
+ * linkgit:git-reset[1] and linkgit:git-checkout[1] (with
+ pathname parameters) to undo changes.
+
+ * linkgit:git-merge[1] to merge between local branches.
+
+ * linkgit:git-rebase[1] to maintain topic branches.
+
+ * linkgit:git-tag[1] to mark a known point.
+
+Examples
+~~~~~~~~
+
+Use a tarball as a starting point for a new repository.::
++
+------------
+$ tar zxf frotz.tar.gz
+$ cd frotz
+$ git init
+$ git add . <1>
+$ git commit -m "import of frotz source tree."
+$ git tag v2.43 <2>
+------------
++
+<1> add everything under the current directory.
+<2> make a lightweight, unannotated tag.
+
+Create a topic branch and develop.::
++
+------------
+$ git checkout -b alsa-audio <1>
+$ edit/compile/test
+$ git checkout -- curses/ux_audio_oss.c <2>
+$ git add curses/ux_audio_alsa.c <3>
+$ edit/compile/test
+$ git diff HEAD <4>
+$ git commit -a -s <5>
+$ edit/compile/test
+$ git diff HEAD^ <6>
+$ git commit -a --amend <7>
+$ git checkout master <8>
+$ git merge alsa-audio <9>
+$ git log --since='3 days ago' <10>
+$ git log v2.43.. curses/ <11>
+------------
++
+<1> create a new topic branch.
+<2> revert your botched changes in `curses/ux_audio_oss.c`.
+<3> you need to tell Git if you added a new file; removal and
+modification will be caught if you do `git commit -a` later.
+<4> to see what changes you are committing.
+<5> commit everything, as you have tested, with your sign-off.
+<6> look at all your changes including the previous commit.
+<7> amend the previous commit, adding all your new changes,
+using your original message.
+<8> switch to the master branch.
+<9> merge a topic branch into your master branch.
+<10> review commit logs; other forms to limit output can be
+combined and include `-10` (to show up to 10 commits),
+`--until=2005-12-10`, etc.
+<11> view only the changes that touch what's in `curses/`
+directory, since `v2.43` tag.
+
+
+Individual Developer (Participant)[[PARTICIPANT]]
+-------------------------------------------------
+
+A developer working as a participant in a group project needs to
+learn how to communicate with others, and uses these commands in
+addition to the ones needed by a standalone developer.
+
+ * linkgit:git-clone[1] from the upstream to prime your local
+ repository.
+
+ * linkgit:git-pull[1] and linkgit:git-fetch[1] from "origin"
+ to keep up-to-date with the upstream.
+
+ * linkgit:git-push[1] to shared repository, if you adopt CVS
+ style shared repository workflow.
+
+ * linkgit:git-format-patch[1] to prepare e-mail submission, if
+ you adopt Linux kernel-style public forum workflow.
+
+ * linkgit:git-send-email[1] to send your e-mail submission without
+ corruption by your MUA.
+
+ * linkgit:git-request-pull[1] to create a summary of changes
+ for your upstream to pull.
+
+
+Examples
+~~~~~~~~
+
+Clone the upstream and work on it. Feed changes to upstream.::
++
+------------
+$ git clone git://git.kernel.org/pub/scm/.../torvalds/linux-2.6 my2.6
+$ cd my2.6
+$ git checkout -b mine master <1>
+$ edit/compile/test; git commit -a -s <2>
+$ git format-patch master <3>
+$ git send-email --to="person <email@example.com>" 00*.patch <4>
+$ git checkout master <5>
+$ git pull <6>
+$ git log -p ORIG_HEAD.. arch/i386 include/asm-i386 <7>
+$ git ls-remote --heads http://git.kernel.org/.../jgarzik/libata-dev.git <8>
+$ git pull git://git.kernel.org/pub/.../jgarzik/libata-dev.git ALL <9>
+$ git reset --hard ORIG_HEAD <10>
+$ git gc <11>
+------------
++
+<1> checkout a new branch `mine` from master.
+<2> repeat as needed.
+<3> extract patches from your branch, relative to master,
+<4> and email them.
+<5> return to `master`, ready to see what's new
+<6> `git pull` fetches from `origin` by default and merges into the
+current branch.
+<7> immediately after pulling, look at the changes done upstream
+since last time we checked, only in the
+area we are interested in.
+<8> check the branch names in an external repository (if not known).
+<9> fetch from a specific branch `ALL` from a specific repository
+and merge it.
+<10> revert the pull.
+<11> garbage collect leftover objects from reverted pull.
+
+
+Push into another repository.::
++
+------------
+satellite$ git clone mothership:frotz frotz <1>
+satellite$ cd frotz
+satellite$ git config --get-regexp '^(remote|branch)\.' <2>
+remote.origin.url mothership:frotz
+remote.origin.fetch refs/heads/*:refs/remotes/origin/*
+branch.master.remote origin
+branch.master.merge refs/heads/master
+satellite$ git config remote.origin.push \
+ +refs/heads/*:refs/remotes/satellite/* <3>
+satellite$ edit/compile/test/commit
+satellite$ git push origin <4>
+
+mothership$ cd frotz
+mothership$ git checkout master
+mothership$ git merge satellite/master <5>
+------------
++
+<1> mothership machine has a frotz repository under your home
+directory; clone from it to start a repository on the satellite
+machine.
+<2> clone sets these configuration variables by default.
+It arranges `git pull` to fetch and store the branches of mothership
+machine to local `remotes/origin/*` remote-tracking branches.
+<3> arrange `git push` to push all local branches to
+their corresponding branch of the mothership machine.
+<4> push will stash all our work away on `remotes/satellite/*`
+remote-tracking branches on the mothership machine. You could use this
+as a back-up method. Likewise, you can pretend that mothership
+"fetched" from you (useful when access is one sided).
+<5> on mothership machine, merge the work done on the satellite
+machine into the master branch.
+
+Branch off of a specific tag.::
++
+------------
+$ git checkout -b private2.6.14 v2.6.14 <1>
+$ edit/compile/test; git commit -a
+$ git checkout master
+$ git cherry-pick v2.6.14..private2.6.14 <2>
+------------
++
+<1> create a private branch based on a well known (but somewhat behind)
+tag.
+<2> forward port all changes in `private2.6.14` branch to `master` branch
+without a formal "merging". Or longhand +
+`git format-patch -k -m --stdout v2.6.14..private2.6.14 |
+ git am -3 -k`
+
+An alternate participant submission mechanism is using the
+`git request-pull` or pull-request mechanisms (e.g as used on
+GitHub (www.github.com) to notify your upstream of your
+contribution.
+
+Integrator[[INTEGRATOR]]
+------------------------
+
+A fairly central person acting as the integrator in a group
+project receives changes made by others, reviews and integrates
+them and publishes the result for others to use, using these
+commands in addition to the ones needed by participants.
+
+This section can also be used by those who respond to `git
+request-pull` or pull-request on GitHub (www.github.com) to
+integrate the work of others into their history. An sub-area
+lieutenant for a repository will act both as a participant and
+as an integrator.
+
+
+ * linkgit:git-am[1] to apply patches e-mailed in from your
+ contributors.
+
+ * linkgit:git-pull[1] to merge from your trusted lieutenants.
+
+ * linkgit:git-format-patch[1] to prepare and send suggested
+ alternative to contributors.
+
+ * linkgit:git-revert[1] to undo botched commits.
+
+ * linkgit:git-push[1] to publish the bleeding edge.
+
+
+Examples
+~~~~~~~~
+
+A typical integrator's Git day.::
++
+------------
+$ git status <1>
+$ git branch --no-merged master <2>
+$ mailx <3>
+& s 2 3 4 5 ./+to-apply
+& s 7 8 ./+hold-linus
+& q
+$ git checkout -b topic/one master
+$ git am -3 -i -s ./+to-apply <4>
+$ compile/test
+$ git checkout -b hold/linus && git am -3 -i -s ./+hold-linus <5>
+$ git checkout topic/one && git rebase master <6>
+$ git checkout pu && git reset --hard next <7>
+$ git merge topic/one topic/two && git merge hold/linus <8>
+$ git checkout maint
+$ git cherry-pick master~4 <9>
+$ compile/test
+$ git tag -s -m "GIT 0.99.9x" v0.99.9x <10>
+$ git fetch ko && for branch in master maint next pu <11>
+ do
+ git show-branch ko/$branch $branch <12>
+ done
+$ git push --follow-tags ko <13>
+------------
++
+<1> see what you were in the middle of doing, if anything.
+<2> see which branches haven't been merged into `master` yet.
+Likewise for any other integration branches e.g. `maint`, `next`
+and `pu` (potential updates).
+<3> read mails, save ones that are applicable, and save others
+that are not quite ready (other mail readers are available).
+<4> apply them, interactively, with your sign-offs.
+<5> create topic branch as needed and apply, again with sign-offs.
+<6> rebase internal topic branch that has not been merged to the
+master or exposed as a part of a stable branch.
+<7> restart `pu` every time from the next.
+<8> and bundle topic branches still cooking.
+<9> backport a critical fix.
+<10> create a signed tag.
+<11> make sure master was not accidentally rewound beyond that
+already pushed out. `ko` shorthand points at the Git maintainer's
+repository at kernel.org, and looks like this:
++
+------------
+(in .git/config)
+[remote "ko"]
+ url = kernel.org:/pub/scm/git/git.git
+ fetch = refs/heads/*:refs/remotes/ko/*
+ push = refs/heads/master
+ push = refs/heads/next
+ push = +refs/heads/pu
+ push = refs/heads/maint
+------------
++
+<12> In the output from `git show-branch`, `master` should have
+everything `ko/master` has, and `next` should have
+everything `ko/next` has, etc.
+<13> push out the bleeding edge, together with new tags that point
+into the pushed history.
+
+
+Repository Administration[[ADMINISTRATION]]
+-------------------------------------------
+
+A repository administrator uses the following tools to set up
+and maintain access to the repository by developers.
+
+ * linkgit:git-daemon[1] to allow anonymous download from
+ repository.
+
+ * linkgit:git-shell[1] can be used as a 'restricted login shell'
+ for shared central repository users.
+
+ * linkgit:git-http-backend[1] provides a server side implementation
+ of Git-over-HTTP ("Smart http") allowing both fetch and push services.
+
+ * linkgit:gitweb[1] provides a web front-end to Git repositories,
+ which can be set-up using the linkgit:git-instaweb[1] script.
+
+link:howto/update-hook-example.html[update hook howto] has a good
+example of managing a shared central repository.
+
+In addition there are a number of other widely deployed hosting, browsing
+and reviewing solutions such as:
+
+ * gitolite, gerrit code review, cgit and others.
+
+Examples
+~~~~~~~~
+We assume the following in /etc/services::
++
+------------
+$ grep 9418 /etc/services
+git 9418/tcp # Git Version Control System
+------------
+
+Run git-daemon to serve /pub/scm from inetd.::
++
+------------
+$ grep git /etc/inetd.conf
+git stream tcp nowait nobody \
+ /usr/bin/git-daemon git-daemon --inetd --export-all /pub/scm
+------------
++
+The actual configuration line should be on one line.
+
+Run git-daemon to serve /pub/scm from xinetd.::
++
+------------
+$ cat /etc/xinetd.d/git-daemon
+# default: off
+# description: The Git server offers access to Git repositories
+service git
+{
+ disable = no
+ type = UNLISTED
+ port = 9418
+ socket_type = stream
+ wait = no
+ user = nobody
+ server = /usr/bin/git-daemon
+ server_args = --inetd --export-all --base-path=/pub/scm
+ log_on_failure += USERID
+}
+------------
++
+Check your xinetd(8) documentation and setup, this is from a Fedora system.
+Others might be different.
+
+Give push/pull only access to developers using git-over-ssh.::
+
+e.g. those using:
+`$ git push/pull ssh://host.xz/pub/scm/project`
++
+------------
+$ grep git /etc/passwd <1>
+alice:x:1000:1000::/home/alice:/usr/bin/git-shell
+bob:x:1001:1001::/home/bob:/usr/bin/git-shell
+cindy:x:1002:1002::/home/cindy:/usr/bin/git-shell
+david:x:1003:1003::/home/david:/usr/bin/git-shell
+$ grep git /etc/shells <2>
+/usr/bin/git-shell
+------------
++
+<1> log-in shell is set to /usr/bin/git-shell, which does not
+allow anything but `git push` and `git pull`. The users require
+ssh access to the machine.
+<2> in many distributions /etc/shells needs to list what is used
+as the login shell.
+
+CVS-style shared repository.::
++
+------------
+$ grep git /etc/group <1>
+git:x:9418:alice,bob,cindy,david
+$ cd /home/devo.git
+$ ls -l <2>
+ lrwxrwxrwx 1 david git 17 Dec 4 22:40 HEAD -> refs/heads/master
+ drwxrwsr-x 2 david git 4096 Dec 4 22:40 branches
+ -rw-rw-r-- 1 david git 84 Dec 4 22:40 config
+ -rw-rw-r-- 1 david git 58 Dec 4 22:40 description

+ drwxrwsr-x 4 david git 4096 Nov 7 14:58 refs
+ drwxrwsr-x 2 david git 4096 Dec 4 22:40 remotes
+$ ls -l hooks/update <3>
+ -r-xr-xr-x 1 david git 3536 Dec 4 22:40 update
+$ cat info/allowed-users <4>
+refs/heads/master alice\|cindy
+refs/heads/doc-update bob
+refs/tags/v[0-9]* david
+------------
++
+<1> place the developers into the same git group.
+<2> and make the shared repository writable by the group.
+<3> use update-hook example by Carl from Documentation/howto/
+for branch policy control.
+<4> alice and cindy can push into master, only bob can push into doc-update.
+david is the release manager and is the only person who can
+create and push version tags.
