I don't have "The Complete FreeBSD," but you are misquoting the bash
man page. What your installation does sounds correct, although there
are a few details that should be explained a little further.
When a login shell starts, bash first executes /etc/profile, if it
exists. After that, it executes *exactly* *one* *of* ~/.bash_profile,
~/.bash_login, and ~/.profile. The first one of those that's found,
wins. The others won't be checked.
.bashrc is executed only by interactive shells that are *not* login
shells. Personally, I don't find this behaviour helpful, so I have
.bash_login automatically drag in .bashrc; but then, the distinction
between login and non-login shells isn't helpful (i.e., you don't
normally *get* a login shell) when you're running under xdm.
If "The Complete FreeBSD" claims that bash automatically executes both
'.profile' and '.bashrc' for the *same* shell, then it's wrong, and
I'm sure Greg Lehey will want to fix that.
Be well.
