not a perl problem: try this shell script instead, it won't work either. the reason is that CRON runs as a daemon, so isn't attached to a tty.<br />

Thanks, kandura. I figured that out yesterday. I discovered that wall -g command works, so I am using that to broadcast a message.

In that case, I suggest you ask for your question to be removed and your points refunded. <br />
I'm just glad I didn't have to go figure out how to find and open tty's ;^)

Hello,<br />
<br />
I have a perl script which gives me the following error when it runs in cron:<br />
<br />
write: can't find your tty<br />
<br />
The purpose of the script is to send a notification to sysadm via the write unix command.<br />
<br />
The script is as follows:<br />
#!/usr/local/bin/perl<br />
$username = &quot;sysadm&quot;;<br />
$message = &quot;here&quot;;<br />
&nbsp; open term, &quot;|/usr/bin/write $username&quot;;<br />
&nbsp; print term $message;<br />
&nbsp; close term;<br />
exit;<br />
<br />
Any ideas on a fix?<br />
<br />
Thanks,<br />

Perl script gives error in cron

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.
