I installed bash and have been trying to set up my prompt. I notice
that if I add

PS1='# '; export PS1

to my .profile, then I get the prompt when I log in, not when I /sudo
su/ from a regular user. If I add

PS1='# '; export PS1

to ~/.bashrc, then I get the prompt when I ``sudo su'', but not when I
log in. I can add the prompt set up to both files, but I'm asking
myself---how do you guys avoid such redundancy? (Thanks!)

Put it in .bashrc and then call .bashrc from .profile (unless
..bash_profile exists; only for bash.)

e.g.
# if running bash
if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
fi
fi

..profile is called by a login shell
..bashrc is called by interactive bash shell

Is this how it's typically done? I thought that sourcing .profile, say,
from .bashrc would destroy the purpose of having a separate thing for
when logging in and another for interactive runs of the shell. Now
realize I could make a library-script and source it from both scripts
(.profile and .bashrc), but then I've never done that myself and so I
was wondering how people do things.

Anyway, thanks very much for sharing your side of things!

No. Source .bashrc from .profile only if $BASH_VERSION is set.
Also .bash_profile will not be used if shell is not bash.

How you do this depends on how you use your shells. There are
"interactive" shells, and "login" shells, and .bashrc is only invoked
under specific conditions. See the bash manual for details, which
afford even more flexibility than most other shells.

Also note that .profile is read and executed by /bin/sh, should you
invoke that shell, and that on FreeBSD, /bin/sh is *not* bash.

In general, there are /four/ modes of shell:

interactive login
interactive non-login
non-interactive login
non-interactive non-login

Which .profile and .rc files are read when is usually
described in the manual for the shell, and I agree with
Wolfgang that the separation of initialisatio between
..profile and .rc scripts is not always clear and sufficient,
so that one has often to add conditional logic and invoke
one from the other.
