Cron problems...

Hi. I seem to be having a bit of a weird problem with crontab on one of my servers. If I log in via SSH, and type;

crontab -l

... it shows the list fine! There is a newline at the bottom of it too, so it should work fine! However, the scripts are not being run :(

I've tried restarting the cron deamon by typing;

/etc/rc.d/init.d/crond restart

.. and that gets the cron deamon started, but it still doesn't like running the crons.

Are there any more things I should try? Any other way to find out why its not running?

TIA.

What are command codes you are using? It could be that you are using unsupported switches in your command codes, or using a different path to execute programs, like bash, php, etc.

You may need to use the full path to perl rather than just perl, like /usr/perl or wherever you perl package exists in the server you are accessing in order to execute your crontab.

Also, try dumping the error message into a text logfile:

> /path/to/logfile.txt for each of your Cron jobs.
