git-sh

A customized bash shell suitable for git work.

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

• All git commands available at top-level (checkout master = git checkout master)
• All git aliases defined in the [alias] section of ~/.gitconfig available at top-level.
• Shawn O. Pearce's excellent bash completion strapped onto all core commands and git aliases.
• Custom prompt with current branch, repository, and work tree dirty indicator.
• Customizable via /etc/gitshrc and ~/.gitshrc config files; for creating aliases, changing the prompt, etc.
• Runs on top of normal bash (~/.bashrc) and readline (~/.inputrc) configurations.

Installation

Install the most recent available version under /usr/local:

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

Start a shell with git-sh:

$ git-sh
master!git-sh> help

Use the PREFIX environment variable to specify a different install location. For example, under ~/bin:

$ make install PREFIX=~

Basic Usage

Typical usage is to change into a git working copy and then start the shell:

$ cd mygreatrepo
$ git sh
master!mygreatrepo> help

Core git commands and git command aliases defined in ~/.gitconfig can be used as top-level commands:

master!mygreatrepo> checkout -b new
new!mygreatrepo> log -p
new!mygreatrepo> rebase -i HEAD~10

It's really just a normal bash shell, though, so all commands on PATH and any aliases defined in ~/.bashrc are also available:

new!mygreatrepo> ls -l
new!mygreatrepo> vim somefile

IMPORTANT: rm, mv, and diff are aliased to their git counterparts. To use system versions, run command(1) (e.g., command rm) or qualify the command (e.g. /bin/rm).

Prompt

The default prompt shows the current branch, a bang (!), and then the relative path to the current working directory from the root of the work tree. If the work tree includes modified files that have not yet been staged, a dirty status indicator (*) is also displayed.

The git-sh prompt includes ANSI colors when 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

Customize prompt colors 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'
$ git config --global color.sh.dirty-stash 'red'
$ git config --global color.sh.repo-state 'red'

See colors in git for information.

Customizing

Most git-sh behavior can be configured by editing the user or system gitconfig files (~/.gitconfig and /etc/gitconfig) either by hand or using git-config(1). The [alias] section is used to create basic command aliases.

The /etc/gitshrc and ~/.gitshrc files are sourced (in that order) immediately before the shell becomes interactive.

The ~/.bashrc file is sourced before either /etc/gitshrc or ~/.gitshrc. Any bash customizations defined there and not explicitly overridden by git-sh are also available.
