Cheat Sheet Title: [ no_spaces_alphanumeric_only ]

Cheat Sheet:
Setup ----- git clone <repo> clone the repository specified by <repo>; this is similar to "checkout" in some other version control systems such as Subversion and CVS Info ---- git diff show a diff of the changes made since your last commit git log show recent commits, most recent on top git show <rev> show the changeset (diff) of a commit specified by <rev>, which can be any SHA1 commit ID, branch name, or tag git blame <file> show who authored each line in <file> git blame <file> <rev> show who authored each line in <file> as of <rev> (allows blame to go back in time) Adding / Deleting ----------------- git add <file1> <file2> ... add <file1>, <file2>, etc... to the project git add <dir> add all files under directory <dir> to the project, including subdirectories git add . add all files under the current directory to the project git rm <file1> <file2> ... remove <file1>, <file2>, etc... from the project Committing ---------- git commit <file1> <file2> ... [-m <msg>] commit <file1>, <file2>, etc..., optionally using commit message <msg>, otherwise opening your editor to let you type a commit message git commit -a [-m <msg>] commit all files changed since your last commit, optionally using commit message <msg> Branching --------- git branch list all branches git branch <branch> create a new branch named <branch>, referencing the same point in history as the current branch git branch <branch> <start-point> create a new branch named <branch>, referencing <start-point>, which may be specified any way you like, including using a branch name or a tag name git branch -d <branch> delete the branch <branch>; if the branch you are deleting points to a commit which is not reachable from the current branch, this command will fail with a warning. git branch -D <branch> even if the branch points to a commit not reachable from the current branch, you may know that that commit is still reachable from some other branch or tag. In that case it is safe to use this command to force git to delete the branch. git checkout <branch> make the current branch <branch>, updating the working directory to reflect the version referenced by <branch> git checkout -b <new> <start-point> create a new branch <new> referencing <start-point>, and check it out. Merging ------- git merge <branch> merge branch <branch> into the current branch; this command is idempotent and can be run as many times as needed to keep the current branch up-to-date with changes in <branch> git merge <branch> --no-commit merge branch <branch> into the current branch, but do not autocommit the result; allows you to make further tweaks git merge <branch> -s ours merge branch <branch> into the current branch, but in the case of any conflicts, the files in the current branch win. Reverting --------- git revert <rev> reverse commit specified by <rev> and commit the result. This does *not* do the same thing as similarly named commands in other VCS's such as "svn revert" or "bzr revert", see below git checkout <file> re-checkout <file>, overwriting any local changes git checkout . re-checkout all files, overwriting any local changes. This is most similar to "svn revert" if you're used to Subversion commands Undo ---- git reset --hard abandon everything since your last commit; this command can be DANGEROUS. If merging has resulted in conflicts and you'd like to just forget about the merge, this command will do that git reset --hard ORIG_HEAD undo your most recent *successful* merge *and* any changes that occurred after. Useful for forgetting about the merge you just did. If there are conflicts (the merge was not successful), use "git reset --hard" (above) instead.

Your cheat sheet will be editable (fixable) by anyone. Each cheat sheet is essentially a wiki page. It may also be used by millions of people for reference purposes from the comfort of their command line. If this is okay with you, please save.
