Most of these programs have intelligible usage messages, or comments
in the source code that explain the usage, or both. My favorites are
git-re-edit. Here is a brief summary of what they do.
git-addq is a simple wrapper around
that gives a menu of dirty files and asks which ones you want added to
the index. Options are passed to
unknown files in the menu.
menupick is available in my util
git-command is a shell alias. If you make a symbolic link, say
commit, that points to
git-command, then you now have a
command that actually runs
git-dirtyfiles lists the files in the repository that have been
edited since the last commit, ignoring unknown files by default, but
including them if you pass
-q. With a commit argument, lists the
files that were changed in that commit. This exists mainly to be a
git-re-edit; see below.
git-fetchs fetches all branches from all the remotes that you have
previously fetched from. This is primarily useful if you have a bunch
of remotes that you don't normally fetch. At a previous employer, we
had a repo setup script that would add one remote for each coworker.
But in most repos I would only want to fetch from the coworkers with
whom I was actually collaborating.
git-ff-branch fast-forwards a branch that might not be checked out.
For example, suppose you do
git fetch remote, find that
remote/master has updated, and you would like to move
remote/master. You can use
git ff-branch master (if
master is set up to track
git ff-branch master
remote/master (if not). Or you can just use
git ff-branch -r
remote to fast-forward all refs that track branches on
command will not modify any head except by fast-forwarding.
git-forcepush is for pushing non-fast-forward updates to branches in
repositories that normally forbid that. It does it by deleting the
old branch first.
git-get retrieves miscellaneous information about the repository.
For example, how does a program retrieve the name of the
currently-checked-out branch? One common answer is the ridiculous
git branch | grep '^\*' | cut -c3-. Another is the equally
git rev-parse --symbolic-full-name --abbrev-ref
git-get you don't have to remember that nonsense: you
git get current-branch-name. To check if the repository is
dirty, you use
git get is-working-tree-dirty and it exits
successfully if so, and unsuccessfully if not. It is easy to drop in
new subcommands; every time I find out there is no easy way to
determine some bit of git information, I drop it in here.
with no argument prints a list of available information.
git-git is the reverse of
git-command. If you accidentally type
git git commit, then
git-git will silently run
git commit for
git-lst lists the files in the specified directory, from
most-recently to least-recently committed, with the last commit times.
It is very much a work in progress; it should have many options, but
[git-ls-date](https://pypi.python.org/pypi/git-ls-date) it is fast
and doesn't fail completely in large repos. The name
lst is supposed
to remind you of
ls -t and also of "LaST changes".
git-quickpush is useful when you want to push commits to a branch
that is frequenty updated by many other people: You fetch the branch,
rebase your commits onto the branch, then push the branch---and the
push fails because someone else pushed to the branch after you fetched
and before you pushed.
git-quickpush does the three operations in
quick succession, and if it fails it's easy to rerun.
git-quickmerge is similar. You specify a branch to merge to, and
some additional options to the
git-merge command, and it fetches the
target branch, merges to it, and pushes it back, again in quick
git-pusho is for pushing local branches to a shared repository. If
your username is
fred and you have branch
topic checked out, then
git pusho is equivalent to
git push origin topic:fred/topic.
Unrecognized options are passed along to
git-dirtyfiles and invokes the editor on all the
currently-dirty files, or if there are no dirty files, the files that
changed in the last commit.
- Suppose you left your working directory dirty when you went home, and for some reason the editor has exited, and you want to open up the editor again to edit the same batch of files. That is the basic use case. You invoke "git re-edit" and it runs the editor on the dirty files.
git reset HEAD^, use
git re-editto invoke the editor on the files that were changed in the last commit.
- During an interactive rebase that results in a complicated merge, you would like to run the editor on the conflicted files to resolve the conflicts.
git re-editwill do that.
- You or a coworker refactors some code. Later, you'd like to refactor the same code some more. Use
git re-editcommit to edit the files that were changed in that commit.
git-todays-commits is supposed to list the commits that I made today.
git-treehash compares the object IDs of the trees of two or more
commits. This tells you if the commits have identical contents. For
example, after a rebase in which commits are reordered, the new commit
should have an identical tree to the original commit.
with no arguments will compare the trees of
If they are identical, it will print out the single hash of the tree.
Otherwise, it will print out both hashes, labeled. Given multiple
commits, it will print out all the tree hashes, each labeled with the
ref names to which it applies, so that you can see which commits have
identical trees and which don't.
git-vee compares two branches, showing the history back to the point
at which they diverged. By default it compares the current
with its remote-tracked branch:
git vee # compare current head branch and its remote tracking branch git vee remote # compare current head branch and its analog on the remote git vee remote branch # compare branch and remote/branch git vee branch # compare HEAD and branch git vee branch1 branch2 # compare branch1 and branch2
Commits are indicated with stars, except that commits that are present
in both branches are indicated with
git-what-changed gets options and arguments like those for
git-log, and then emits the filenames, and only the filenames, that
have been changed in the selected commits. By default this lists the
changed files in reverse chronological order. I have an alias,
myfiles, which means
git what-changed --author=mjd, which lists the
files I have recently touched.
git-whats records a description for a branch, or prints a previously
trim is not really a git command. It trims trailing whitespace from
the files named in its arguments.
conf/dot-gitignore contain my personal
bash_completion.d contains completion scripts, which, if sourced,
will enable bash command-line completion for some of these commands.
A discussion of how I use some of these tools is available at My Git Habits.
