-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I find its generally a lot easier to just have cron run a script file. In the script file is where you do all the metacharacters, date formatting, special programming, etc. You can test you script by running it from the command line until you know its working perfectly then add a cron entry to run your script whenever you wish. Adding a fancy entry with lots of arguments in the crontab itself, and then having to wait for it to run when schedualed, just to see if it worked can be a real pain. Just my 2 cents for what its worth (About 1/4 of apenny these days!) - ----- Original Message ----- From: "ann kok" <annkok2001@yahoo.com> To: "Jan Grant" <Jan.Grant@bristol.ac.uk> Cc: "questions" <questions@FreeBSD.ORG> Sent: Tuesday, January 15, 2002 9:47 PM Subject: Re: crontab to backup mail in date format > --- Dear Jan > > Thank you.
