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.
|
||||
|
||||
* howto/update-hook-example has a good example of
|
||||
managing a shared central repository.
