Just BTW, a *much* more reliable way to check for an interactive
session, which will not fail in many common cases (PS1 set in system-wide
config files, PS1 also set in .bashrc, PS1 set in the environment of
the calling shell, etc.), is the following:
# First, set up all variables for both interactive and non-interactive
# sessions.
# Then, do this:
case "$-" in
*i*)
echo 'Setting up interactive shell params..'
stty erase ^H
;;
*)
# Non-interactive session, better don't output anything
something_or_other=foo
;;
esac
Of course, substitute your own commands for the "stty" and the assignment :)
Bear in mind that this only applies to Bourne-style shells;
for tcsh, you might need to resort to testing for ($?prompt), indeed.
G'luck,
Peter
