Show Git / Mercurial / SVN / Bazaar branch in the Bash prompt

Clipart image of a blank command prompt
This is my solution for modifying the Bash prompt (PS1) to show the branch name. It works for any working directory in a Git, Mercurial, Subversion or Bazaar branch. [2 minutes]

The function works by looking for a .git, .hg, .svn or .bzr in any of the ancestor directories, and if found uses appropriate commands like __git_ps1, hg branch, svn info to deduce the branch name to prepend to the PS1 prompt.  For Bazaar it avoids the slow "bzr nick" command by looking in branch.conf directly. Here is the embedded gist:



Here is a link to the show branch name in Bash prompt gist, for when the embedding is not displaying.

Super handy if you have lots of checkouts all over the place!

P.S. if you are into working more efficiently, try this summary of Time Management for System Administrators (applies just as much to DevOps and SRE).
