Re: which file should have my bash prompt, .profile vs .bashrc

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
