+Everyday GIT With 20 Commands Or So
+===================================
+
+GIT suite has over 100 commands, and the manual page for each of
+them discusses what the command does and how it is used in
+detail, but until you know what command should be used in order
+to achieve what you want to do, you cannot tell which manual
+page to look at, and if you know that already you do not need
+the manual.
+
+Does that mean you need to know all of them before you can use
+git? Not at all. Depending on the role you play, the set of
+commands you need to know is slightly different, but in any case
+what you need to learn is far smaller than the full set of
+commands to carry out your day-to-day work. This document is to
+serve as a cheat-sheet and a set of pointers for people playing
+various roles.
+
+<<Basic Repository>> commands are needed by people who has a
+repository --- that is everybody, because every working tree of
+git is a repository.
+
+In addition, <<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
+<<Individual Developer (Participant)>> section as well.
+
+People who play <<Integrator>> role need to learn some more
+commands in addition to the above.
+
+<<Repository Administration>> commands are for system
+administrators who are responsible to care and feed git
+repositories to support developers.
+
+
+Basic Repository[[Basic Repository]]
+------------------------------------
+
+Everybody uses these commands to feed and care git repositories.
+
+ * gitlink:git-init-db[1] or gitlink:git-clone[1] to create a
+ new repository.
+
+ * gitlink:git-fsck-objects[1] to validate the repository.
+
+ * gitlink:git-prune[1] to garbage collect crufts in the
+ repository.
+
+ * gitlink:git-repack[1] to pack loose objects for efficiency.
+
+Individual Developer (Standalone)[[Individual Developer (Standalone)]]
+----------------------------------------------------------------------
+
+A standalone individual developer does not exchange patches with
+other poeple, and works alone in a single repository, using the
+following commands.
+
+ * gitlink:git-show-branch[1] to see where you are.
+
+ * gitlink:git-diff[1] and gitlink:git-status[1] to see what
+ you are in the middle of doing.
+
+ * gitlink:git-log[1] to see what happened.
+
+ * gitlink:git-whatchanged[1] to find out where things have
+ come from.
+
+ * gitlink:git-checkout[1] and gitlink:git-branch[1] to switch
+ branches.
+
+ * gitlink:git-update-index[1] to manage the index file.
+
+ * gitlink:git-commit[1] to advance the current branch.
+
+ * gitlink:git-reset[1] and gitlink:git-checkout[1] (with
+ pathname parameters) to undo changes.
+
+ * gitlink:git-pull[1] with "." as the remote to merge between
+ local branches.
+
+ * gitlink:git-rebase[1] to maintain topic branches.
+
+
+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.
+
+ * gitlink:git-pull[1] from "origin" to keep up-to-date with
+ the upstream.
+
+ * gitlink:git-push[1] to shared repository if you adopt CVS
+ style shared repository workflow.
+
+ * gitlink:git-format-patch[1] to prepare e-mail submission, if
+ you adopt Linux kernel-style public forum workflow.
+
+
+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.
+
+ * gitlink:git-am[1] to apply patches e-mailed in from your
+ contributors.
+
+ * gitlink:git-pull[1] to merge from your trusted lieutenants.
+
+ * gitlink:git-format-patch[1] to prepare and send suggested
+ alternative to contributors.
+
+ * gitlink:git-revert[1] to undo botched commits.
+
+ * gitlink:git-push[1] to publish the bleeding edge.
+
+
+Repository Administration[[Repository Administration]]
+------------------------------------------------------
+
+A repository administrator uses the following tools to set up
+and maintain access to the repository by developers.
+
+ * gitlink:git-daemon[1] to allow anonymous download from
+ repository.
+
+ * gitlink:git-shell[1] can be used as a 'restricted login shell'
+ for shared central repository users.
+
+ * link:howto/update-hook-example.txt[update hook howto] has a
+ good example of managing a shared central repository.

-'git-show-branch [--all] [--heads] [--tags] [--more=<n> | --list | --independent | --merge-base] [--no-name | --sha1-name] <reference>...'
+'git-show-branch [--all] [--heads] [--tags] [--topo-order] [--more=<n> | --list | --independent | --merge-base] [--no-name | --sha1-name] [<rev> | <glob>]...'
DESCRIPTION
-----------
-Shows the head commits from the named <reference> (or all refs under
-$GIT_DIR/refs/heads), and displays concise list of commit logs
-to show their relationship semi-visually.
+
+Shows the commit ancestry graph starting from the commits named
+with <rev>s or <globs>s (or all refs under $GIT_DIR/refs/heads
+and/or $GIT_DIR/refs/tags) semi-visually.
+
+It cannot show more than 29 branches and commits at a time.
+
OPTIONS
-------
-<reference>::
- Name of the reference under $GIT_DIR/refs/.
+<rev>::
+ Arbitrary extended SHA1 expression (see `git-rev-parse`)
+ that typically names a branch HEAD or a tag.
+
+<glob>::
+ A glob pattern that matches branch or tag names under
+ $GIT_DIR/refs. For example, if you have many topic
+ branches under $GIT_DIR/refs/heads/topic, giving
+ `topic/*` would show all of them.
--all --heads --tags::
Show all refs under $GIT_DIR/refs, $GIT_DIR/refs/heads,
and $GIT_DIR/refs/tags, respectively.
+--topo-order::
+ By default, the branches and their commits are shown in
+ reverse chronological order. This option makes them
+ appear in topological order (i.e., descendant commits
+ are shown before their parents).
+
--more=<n>::
Usually the command stops output upon showing the commit
that is the common ancestor of all the branches. This

useful when the file is available, but you do not wish to update the

+
+Using --index-info
+------------------
+
+`--index-info` is a more powerful mechanism that lets you feed
+multiple entry definitions from the standard input, and designed
+specifically for scripts. It can take inputs of three formats:
+
+ . mode SP sha1 TAB path
++
+The first format is what "git-apply --index-info"
+reports, and used to reconstruct a partial tree
+that is used for phony merge base tree when falling
+back on 3-way merge.
+
+ . mode SP type SP sha1 TAB path
++
+The second format is to stuff git-ls-tree output
+into the index file.
+
+ . mode SP sha1 SP stage TAB path
++
+This format is to put higher order stages into the
+index file and matches git-ls-files --stage output.
+
+To place a higher stage entry to the index, the path should
+first be removed by feeding a mode=0 entry for the path, and
+then feeding necessary input lines in the third format.
+
+For example, starting with this index:
+
+------------
+$ git ls-files -s
+100644 8a1218a1024a212bb3db30becd860315f9f3ac52 0 frotz
+------------
+
+you can feed the following input to `--index-info`:
+
+------------
+$ git update-index --index-info
+0 0000000000000000000000000000000000000000 frotz
+100644 8a1218a1024a212bb3db30becd860315f9f3ac52 1 frotz
+100755 8a1218a1024a212bb3db30becd860315f9f3ac52 2 frotz
+------------
+
+The first line of the input feeds 0 as the mode to remove the
+path; the SHA1 does not matter as long as it is well formatted.
+Then the second and third line feeds stage 1 and stage 2 entries
+for that path. After the above, we would end up with this:
+
+------------
+$ git ls-files -s
+100644 8a1218a1024a212bb3db30becd860315f9f3ac52 1 frotz

+Advanced Shared Repository Management
+-------------------------------------
+
+Being able to push into a shared repository means being able to
+write into it. If your developers are coming over the network,
+this means you, as the repository administrator, need to give
+each of them an SSH access to the shared repository machine.
+
+In some cases, though, you may not want to give a normal shell
+account to them, but want to restrict them to be able to only
+do `git push` into the repository and nothing else.
+
+You can achieve this by setting the login shell of your
+developers on the shared repository host to `git-shell` program.
+
+[NOTE]
+Most likely you would also need to list `git-shell` program in
+`/etc/shells` file.
+
+This restricts the set of commands that can be run from incoming
+SSH connection for these users to only `receive-pack` and
+`upload-pack`, so the only thing they can do are `git fetch` and
+`git push`.
+
+You still need to create UNIX user accounts for each developer,
+and put them in the same group. Make sure that the repository
+shared among these developers is writable by that group.
+
+You can implement finer grained branch policies using update
+hooks. There is a document ("control access to branches") in
+Documentation/howto by Carl Baldwin and JC outlining how to (1)
+limit access to branch per user, (2) forbid overwriting existing
+tags.
