This is a good general solution, but the \u makes the prompt longer than
it needs to be in lots of cases, particularly when you're really deep
in a directory tree. For the machines where I'm the only person who
has root, I put this in ~root/.bashrc :
...making the shell prompt show up in red in root shells, providing a
great visual cue that reminds me to double-check each command line
before hitting Return.
For those machines where I'm not the only person who has root, I put
this in ~root/.bashrc :
...so all the other users don't go "huh?" when they see a prompt they
aren't expecting, and all I have to do to get a familiar prompt is
"export PS1=$MGPS1" after su'ing.
(I *really* don't like the default Redhat prompt that uses \W instead of
\w and puts useless s in PS1. \W I can almost see the reasons for,
the brackets seem totally silly.)
