What have you done so far to learn about cron? It's quite possible to run Perl programs through Cron, so I'm not sure how to help you more. Usually, you can also configure your crontab entries to set up the recipient of the email directly. `cron` will then send mail to the configured account using the local mail sending mechanism.

Firstly I want to know whether it is possible to schedule the running of a perl script using cron or not. Cron doesn't care at all in which language your program is written. If it is possible kindly help me out. Actually, how to use cron isn't a Perl question. Have you read the `cron` and `crontab` manual pages?	[reply]

You might also look at `at` depending on what your use case is. `at` inherits almost all of its invoker's environment, while `cron` gets pretty near none of it, which can lead to some frustration. In any event, the code on the end of your post is entirely superfluous, and as others have said, how to get cron working isn't a Perl issue at all. Cron pays no attention whatsoever to details of the commands you give it, it just runs them at the specified time in a clean environment. If it's an executable and properly constructed, it will execute. If it's not, it won't. Also of course, the standard advice for stuff like this--try it and see what happens.	[reply] [d/l] [select]

You'll have to make sure that your script has the right permissions to run through the cron. Then simply add the following to crontab to make it run every day at 10 AM `* 10 * * * /path/to/your/script.pl` [download] You might want your cron to suppress output, which make the line above as follows: `* 10 * * * /path/to/your/script.pl > /dev/null 2>&1` [download]	[reply] [d/l] [select]
