This chapter is about inter-operation between Git and other systems.

Git is a great version control system, but it is not the only one. Many projects still use version control systems that predate git or alternate DSCMs. Thankfully, you can still use git to participate in many of these projects, thanks to programs like git-svn, git-cvsimport, etc.

You can also work with Git directly within many text editors, IDEs and other tools.

Customizing your command line prompt

[edit | edit source]

This Bash customization script will modify your command line prompt to include some extra details whenever you're in a Git directory. It is based on Mike Stewart's work.[1]

The current branch name is shown in red (if it's got outstanding changes) or green (if there are no changes), followed by the current path. The hostname is also shown in a low-lighted colour at the beginning.

Green="\[\033[0;32m\]"        # Green
Yellow="\[\033[0;33m\]"       # Yellow
Red="\[\033[0;91m\]"          # Red
Hostname="\h"                 # Hostname (up to the first dot)

  # Prompt when not in GIT repo
  echo " '$Yellow$PathShort$Color_Off'\$ "; \
