Yes, of course :-)

Agreed.  My current .bash_profile is basically a minimal wrapper around
.bashrc these days:

% gothmog % cat -n .bash_profile
%      1  # Startup file for login instances of the bash(1) shell.
%      2  # $RCS: giorgos/.bash_profile,v 1.10 2005/07/10 21:10:39 giorgos Exp $
%      3
%      4  # First of all, run a .bashrc file if it exists.
%      5  test -f ~/.bashrc && . ~/.bashrc
%      6
%      7  # The following section should be pretty minimal, if present at all.
%      8  mesg y >/dev/null 2>&1
%      9  /usr/bin/true
% gothmog %
