My custom BASH prompt setup

gistfile1.txt

This incorporates the file directory name I'm in (in purple), as well as the git branch I'm in (in green), in brackets
 
export PS1='\[\033[01;34m\]\W\[\033[00m\] [$(__git_ps1 "\[\033[01;32m\]%s\[\033[00m\]")] $ '
 
Colorless
export PS1='\W [$(__git_ps1 "%s")] $ '
 
Gray bold with green - the one I've settled on for now
export PS1='\[\033[01;02m\]\W\[\033[00m\] $(__git_ps1 "[\[\033[01;32m\]%s\[\033[00m\]]") $ '

For my record, my original prompt is export PS1='\h:\W \u\$'
