A customized bash shell suitable for git work.

The git-sh command starts an interactive bash shell tweaked for heavy git interaction:

• Makes all git command porcelains available as top-level command aliases.
• Custom prompt with branch and current repository.
• Shawn O. Pearce's bash completion support built-in.
• Customizable via /etc/gitshrc and ~/.gitshrc config files (add aliases, change prompt, etc.)
• gitalias command for defining shorthand git aliases with completion.
• Respects ~/.bashrc and ~/.inputrc configuration.

I suppose we can assume you have git installed:

$ git clone git://github.com/rtomayko/git-sh.git
$ cd git-sh
$ make
$ sudo make install

The make install command copies the git-sh executable to /usr/local/bin. Use the PREFIX environment variable to specify a different location (or just copy and chmod the git-sh file).

If you'd like to be able to run git sh instead of git-sh, use the following to add a command alias in ~/.gitconfig:

$ git-sh --configure
$ git sh

The git-sh prompt includes ANSI color support but it's disabled by default (unless the git color.ui option is enabled). To enable git-sh's prompt colors explicitly, set the color.sh config value to auto:

$ git config --global color.sh auto

The prompt colors can be customized by setting the color.sh.branch, color.sh.workdir, and color.sh.dirty git config values:

$ git config --global color.sh.branch 'yellow reverse'
$ git config --global color.sh.workdir 'blue bold'
$ git config --global color.sh.dirty 'red'

See colors in git for information on customizing.

I typically change into a git working copy before starting the shell:

$ cd some-git-repo
$ git sh
master!some-git-repo>

The shell's default prompt shows the current branch, a bang, and the relative path to the current working directory from the nearest git working copy.

Most git commands can be executed directly:

master!some-git-repo> checkout -b new-branch
new-branch!some-git-repo> log -p
new-branch!some-git-repo> rebase -i HEAD~10

IMPORTANT: rm, mv, and diff are aliased to their git counterparts. Use the command command (eg. command rm) or qualify the command (e.g. /bin/rm) to use system versions.

The /etc/gitshrc and ~/.gitshrc files are sourced (in that order) immediately before the shell becomes interactive. An example gitshrc file is include in the distribution as an example.

Note also that your ~/.bashrc file is sourced into the shell before either /etc/gitshrc or ~/.gitshrc, so any base bash customizations not explicitly overridden by git-sh should be available.

The help command shows git's help output followed by a list of custom aliases from your ~/.gitshrc file:

master!some-git-repo> help
