Is there a way to change the prompt on a different directories on the same machine? For example, I want a simple prompt "[\W] \$" in development directories.
Ideas?

Force prompt on specific directories

You can put something like this in your .bashrc.
prompt-function() {
case $PWD in
/a/dev/dir\
|/another/dev/dir)
PS1="[\W] \$"
;;
*)
# Change this to the default prompt
PS1="\$ "
;;
esac
}
PROMPT_COMMAND=prompt-function

+1 I would use a case statement instead of a series of elsif statements. You could even put the directories in an array and iterate over them with a for loop. You could use globbing patterns with any of those techniques or you could use regexes with [[ $PWD =~ $pattern ]]. – Paused until further notice. – 2011-01-01T19:13:08.560
@Dennis: I edited my answer with a case statement. Thanks for the suggestion. – Wuffers – 2011-01-01T19:16:49.297
If the action is the same, you can list the action once after alternative cases separated by pipe characters. foo|bar) action;; You can put the cases on separate lines by putting a backslash and newline before or after the pipe character. – Paused until further notice. – 2011-01-01T21:47:42.843
@Dennis: Edited my answer accordingly, again. Thanks for the suggestion! – Wuffers – 2011-01-01T21:58:05.007
1It depends on which shell you're using. – Paused until further notice. – 2011-01-01T19:09:24.400
