don't use Gnome/KDE as often, so can't comment on them).
~/.bashrc gets sourced when ever you open an interactive shell,
maybe by
opening a terminal emulator or login in remotely.
This means whenever you login remotely both ~/.bash_profile&
~/.bashrc
gets sourced. However if you open a terminal emulator like
gnome-terminal or xterm only your ~/.bashrc gets sourced.
It is my impression that.bashrc is souurced whenever any program
is run
in a bash environment. I am willing to be corrected.
By bash environment if you mean a terminal emulator then that is
exactly what I meant in my previous post. However if for example you
run something using a menu or shortcut on your desktop or maybe
Alt-F2 then ~/.bashrc is _not_ sourced, and environment variables
defined there won't be available to you. If you want something like
that, you need to define it in your ~/.bash_profile.
Hope this makes my point clearer. :)
Naive question .... it sounds like if a user has selected bash as
shell-of-choice, then bash_profile is there for any operation
(terminal or not) that would involve the use of the shell? I might not
be saying this right, but I am trying to understand just how global
bash_profile is and, if not, why it isn't as it seems by your email
that for all intents and purposes it is global to a user's login
process.
Thanks for bearing with the question given that you already know I am
running tcsh and therefore this is a learning exercise as opposed to a
real occurrence in my usage of fedora.

Why not just read "man bash"?
Because bring up the "man bash" pages and searching for "profile"
gives me info about what happens with a shell or a non-interactive
--login shell and doesn't give me any meta information that either
answers my question or makes it clear that I am asking the wrong
question.

One of the reasons to watch/read this forum is to get answers to
questions that man pages don't supply. In my experience, if you want
to know exactly how to do something with a given command/whatever,
they are great. If you want to get an understanding of the overall
picture of the command/whatever, they aren't very good as they assume
you have already commit to "this is what I am using so how do I do
this particular operation".
To ask what is the scope of ".bash_profile" outside of sourcing order
in particular occurrences, I don't see it in the man pages.
I am more than happy to be told that I am totally incorrect in my
interpretation of this.
Thanks (and that includes making me double-check the man pages to
prove to myself that I am not seeing the answer I am looking for!),
Paul
I suppose I don't understand your question or what makes you think the
man page doesn't answer it.....
The man page tells you under what conditions the various files
(/etc/profile, ~/.bash_profile ~/.bash_login etc) are read depending on
what type of shell (interactive, login).
Are you saying there is a situation not covered?
Remember, everything that is executed is executed under a shell.
Ed,
Thanks for bearing with me on this.
I think part of my confusion is that I am not understanding whether a
login shell covers everything that is done once I have logged in via
splash screen or if it is confined to "logining into a shell". If the
former, then I would assume bash_profiles is hit once and everything
done thereafter would be under its command. If the latter, then I am
probably unclear about whether launching a terminal is a "login" act
(hence under bash_profile only within that shell).
As I said on my initial reply to this thread, "Naive question". I may be
missing a fundamental understanding of shells and logins and all that
sort of stuff.
Paul
