Crontab

Hello. I understand the basics of crontab. I added two entries to my crontab file a few months ago and now they don't work any more. I haven't done anything to the script in the crontab file nor I have done anything to the file that the scripts output to.

Any suggestions of where I should look to resolve this problem? I'm still fairly new with using UNIX. Thanks!

couple of things come to mind.

cron isn't running? This is a daemon that executes crontab.

Your crontab access has been removed. If you are listed in /etc/cron.d/cron.deny(if exists) or not in /etc/cron.d/cron.allow.

Check your man page...man -k for more info

Hello,

somebody can have changed the PATH variable, too. Check your mail, where you can find some hints. If I were you, I would redirect the stdout and stderr from your cron job into files. It makes it possible to catch the error messages easily.

Regards

Hmmm... I think I found the problem. First, thanks for the help. I was sure cron was running because two other scripts were working. I checked the /usr/lib/cron/log file and noticed that the two scripts in question were in that file. So, I decided to try and run the scripts manually and that didn't work. I got an argument of "execute permission denied." I checked the permissions on the scripts and they weren't right.

Now I'm wondering how and why the permissions changed?!?!
