I've got an /etc/printcap (permissions = -rw-r--r-- root root) that looks
like:
beeper:\
:if=/home/westk/beeper-filter:\
:lp=/dev/null:\
:sd=/var/spool/lpd/beeper:
(permissions on /var/spool/lpd/beeper = -drwxrwxr-x lp lp)
and a /home/westk/beeper-filter (permissions = -rwxr-xr-x root root) that
looks like:
#!/usr/bin/perl
$recipient = "[EMAIL PROTECTED]";
$subject = "Beeper Message";
$mailprog = "mail";
open (MAIL, "|$mailprog -s \'$subject\' $recipient");
print MAIL "------------ Header Line\n\n";
while (<STDIN>) {
print MAIL $_;
}
print MAIL "\n------------ Footer Line\n";
close MAIL;
As root in any non-empty directory (such as /etc), I'm typing
ls -l|lpr -Pbeeper
Then four files appear in the spool directory and stay until I rm them,
and the mail message is apparently never generated (at least it never
shows up in my mailbox).
I've also tried putting a
print "Text";
just after the
#!/usr/bin/perl
line, but I never see the test message printed. However, I just realized,
could the test message be printing to /dev/null? If so, how do I redirect
the test message to my screen so that I can verify that the beeper-filter
is being run when I print something?
(Thanks to Jim Foltz for getting me this far, esp the basic script.)
