Well, I used the below method to implement the prompt along with # for
superuser and $ for user. However it only updates with cd, not chdir.
# set prompt and display it at start up before any cd command is used
case `id -u` in
0) PS1="`pwd`# ";; # for root... uid 0
*) PS1="`pwd`$ ";;
esac
# update prompt with each cd -- will NOT update if chdir is used though
cd() {
chdir "$@"
case `id -u` in
0) PS1="`pwd`# ";;
*) PS1="`pwd`$ ";;
esac
}
However I still don't know how to make the # at the end of my csh prompt
expand to % for user and # for superuser. It's just static at # for all
users. But it does update the directory so thanks to everyone who helped
out! Shells are such a chore. I'm gonna have to get myself one of those
shell books.
Thanks!
