Re: need help with ~/.bash_profile

[gregory mott <gmott ntlworld com>]

the shipped redhat(7.x) arrangement of bashrc's & profile's is confusing
and incorrectly documented.  i evolved to this solution:

discard /etc/skel/.bash_profile before creating any users
replace /etc/profile and /etc/bashrc

i leave /etc/skel/.bashrc in place.  it contains merely an invocation of
/etc/bashrc

similarly, my replacement /etc/profile merely contains an invocation of
~/.bashrc

for login shells, bash itself only invokes /etc/profile
for non login shells, bash itself only invokes ~/.bashrc

hence, in my setup, we get to /etc/bashrc in either case.  the
simplicity of this avoids much confusion about which shell invocations
are like logins and which aren't.  and i see no practical concern about
putting environment and function declarations all together.

otoh functions which in turn invoke aliases only work properly when the
file that defines them is conditionally invoked, not invoked if the
shell is not an interactive shell.  so, in my setup, all my stuff is
actually in /etc/bashrc+, which /etc/bashrc only invokes in interactive
shells.

my actual files are included below.

I have CLASSPATH settings for my shell in this file and have to manually source it with each new shell I use. Annoying.
