		Toucan on Jan 10, 2011 \| parent \| context \| favorite \| on: Production is Red, Development is Blue You could put a shell script around cd that checks the current working directory every time you cd and alerts you appropriately. A little clunky, I'll admit. I'd like to hear any more graceful solutions.

From man bash, the variable PROMPT_COMMAND:

  If set, the value is executed as a command prior to issuing each primary prompt.

e.g.:

  PROMPT_COMMAND='[[ "$PWD" =~ ^/sensitive/area ]] && PS1="be careful: " || PS1="normalprompt: "'
