3 # Prompt is user@host:/dir$ where host is highlighted in green if the last
4 # command exited 0 or in red (followed by the error code) otherwise.
6 # Colouring is performed by the __ps1_col() and __ps1_ret() functions.
7 # We redirect stderr to /dev/null when calling these functions to prevent
8 # bash complaining about not knowing them when you su to another user,
9 # retaining PS1 but not the function definitions.
11 # To use, add a call to __ps1 in your .bash_profile file.
