Just to be precise and complete...

That's almost correct.  Your *are* allowed to generate output in
.bashrc (and in .cshrc for tcsh) for *interactive* shells only.  The
usual way to test is to check for the existence of a prompt.  ($PS1 in
bash, $prompt in tcsh.)  If no prompt is defined, you must not
generate *any* output.

Hope this helps.

Regards,
David
