Appendix A Git Command Cheat Sheet
**********************************
This major node provides an alphabetical list of the Git commands cited
in this Info file, along with brief descriptions of what the commands
do.
Note that you may always use either 'git help COMMAND' or 'git
COMMAND --help' to get short, man-page style help on how to use any
given Git command.
'git add'
Add a file to the list of files to be committed.
'git branch'
View existing branches, or delete a branch. Most useful options:
'-a' and '-d'.
'git checkout'
Checkout an existing branch, create a new branch, or checkout a
file to reset it. Use the '-b' option to create and checkout a new
branch in one operation.
'git clone'
Clone (make a new copy of) an existing repository. You generally
only need to do this once.
'git commit'
Commit changes to files which have been staged for committing with
'git add'. This makes your changes permanent, _in your local
repository only_. To publish your changes to an upstream repo, you
must use 'git push'.
'git config'
Display and/or change global and/or local configuration settings.
'git diff'
Show a unified-format diff of what's changed in the current
directory as of the last commit. It helps to have Git configured
to use its builtin pager for reviewing diffs (
Configuring
git).
'git difftool'
Use a "tool" (usually a GUI-based program) to view differences,
instead of the standard textual diff as you'd get from 'git diff'.
'git fetch'
Update your local copy of the upstream's branches. That is, update
the various 'origin/' branches. This leaves your local tracking
branches unchanged. With the '--prune' option, this removes any
copies of stale 'origin/' branches.
'git format-patch'
Create a series of patch files, one per commit not on the original
branch from which you started.
'git gc'
Run a "garbage collection" pass in the current repository. This
can often reduce the space used in a large repo. For 'gawk' it
does not make that much difference.
'git help'
Print a man-page-style usage summary for a command.
'git log'
Show the current branch's commit log. This includes who made the
commit, the date, and the commit message. Commits are shown from
newest to oldest.
'git merge'
Merge changes from the named branch into the current one.
'git pull'
When in your local tracking branch 'XXX', run 'git fetch', and then
merge from 'origin/XXX' into 'XXX'.
'git push'
Push commits from your local tracking branch 'XXX' through
'origin/XXX' and on to branch 'XXX' in the upstream repo. Use 'git
push -u origin --delete XXX' to delete an upstream branch. (Do so
carefully!)
'git rebase'
Rebase the changes in the current purely local branch to look as if
they had been made relative to the latest commit in the current
upstream branch (typically 'master'). This is how you keep your
local, in-progress changes up-to-date with respect to the original
branch from which they were started.
'git reset'
Restore the original state of the repo, especially with the
'--hard' option. Read up on this command, and use it carefully.
'git status'
Show the status of files that are scheduled to be committed, and
those that have been modified but not yet scheduled for committing.
Use 'git add' to schedule a file for committing. This command also
lists untracked files.
