I am sure that is the case.

Not on Debian.  I think you must be thinking of a different system. :-)

You are probably confused by the fact that Debian's xdm, kdm, gdm
login does not start the user shell as a login shell and so the
~/.bash_profile is not sourced at login the same as a text console
login.  Create a ~/.xsession as a login shell as already described
several times this week on this list and it will source your
~/.bash_profile at login.

All of your questions are answered in the man page, under INVOCATION.

 ~/.bash_rc is not a standard file; do you mean ~/.bashrc?

 /etc/bash.bashrc is usually sourced in /etc/profile.

 Both files can be sourced any time you want them to be.

man bash:

   A login shell is one whose first character of argument zero  is  a
   -, or one started with the --login option.

   An  interactive  shell is one started without non-option arguments
   and without the -c option whose standard input and error are  both
   connected  to  terminals  (as  determined  by  isatty(3)),  or one
   started with the -i option.  PS1 is set and $- includes i if  bash
   is  interactive, allowing a shell script or a startup file to test
   this state.

  If you call xterm with the -ls option, it opens a login shell,
  i.e., one which sources /etc/profile and ~/.bash_profile.

  If the shell is interactive, but not a login shell (e.g., xterm
  without -ls), it sources ~/.bashrc.

bash startup scripts - what is an "interactive login" ??

[Mark D. Hansen]

Can anyone clarify for me when the ~/.bash_rc and /etc/bash.bashrc scripts get 
sourced?  I read from the man and googling that it is only when an "interactive 
login" shell is created, but what does that mean?  If I create a new xterm do 
these scripts get sourced or is it only if I do an rlogin, ssh, login ,etc?

Thanks,

Mark
