My prompt executes a couple of commands to display the current Ruby version and the current git status, and then I want to use the exit status of the last command to control the colour of the final character (e.g. $).

Thanks everyone for your help and suggestions.  It was interesting looking at the different solutions.  In the end I went with Viktor's method of setting up PS1 in PROMPT_COMMAND.

As for switching to zsh, I've intended to ever since reading "From Bash to Z Shell" by Kiddle, Peek, and Stephenson about three years ago!  One day I'll switch.

Thanks again,
Andy
