A small bash script that detects if your current directory is managed by Subversion or Git and shows you the branch you're in on your prompt

  1. #!/bin/bash
  2.  
  3. #
  4. # Show your SCM path/branch information on the prompt.
  5. # Currently works with subversion or git.

  7. # OSX: set your prompt like so in ~/.profile
  8. #    export PS1='\h:\W \u`source ~/scmprompt.bash`\$ '
