Well, let's first consider the following ideas, instead:
- Use msgs(1). RTFM for details, but this involves enabling msgs in
/etc/profile and /etc/csh.login (there's already samples there), and
a few other changes. After it's all set up, then you can send email
to "msgs" to make an announcement to all users that will be seen by
each on their next login.
- Use motd(5); that's what it's for.
If these are unsuitable, then here's a script. Just send this message
to a file, modify the subject line (presently "Yow!...") and the
message text, and run 'perl -x' on it.
Happy hacking,
joelh

This is a test. This is only a test. If this had been an actual
message, it would contain useful information.
EOT
close MSG;
