Hi all Me again. I am new to learning how things like cron etc work in Linux (as opposed to AT etc in NT environments). My understanding is, you put a line into the /etc/crontab file and the system automatically reads that file once per minute. Now, I want to run a script at, say, 14h30, so I put in my /etc/crontab file: 30 14 * * * root /usr/bin/perl /home/default/scriptname.pl some_argument Is this correct? Well, I know it's not correct, because I did that a few minutes ago (different time :-)) and at the appointed time, nothing happened. Basically, I want to know how to tell the system to run a specific perl script at a certain time, and to accept a command line argument. How can I do this?
