Shell-script question

[Andre Berger]

I wrote a shell script "/usr/local/bin/mailcheck" (/usr/local/bin/ is in
$PATH of my potato bash) that gives a list of pon "targets" (diff.
ISPs), and is owned by root., perms 755. I've virtually no experience
with shell scripting, so it may be poor quality. Anyway: If the script
is invoked from a command line within or outside X, it works.  If it's
invoked via "rxvt -e mailcheck" or "rxvt -ls -e mailcheck", everything
looks normal, but nothing's dialed.
