I have read quite some bit about Cron and crontab,am new to Linux and am just getting to know some of the utilities.
Can someone please guide me through some practical Examples of how to use cron.
I need examples i can follow step by step without having to wonder how or what next to do.I will also appreciate the output to be shown so that as i follow,am able to see how this utility works.
Examples can include but not limited to;
1.how to add a cron job to send a timestamp to a file
2.how to add a cron job that displays a gui interface
and other examples where this utility can be applied.
Am running Centos 5 Linux operating system.Your help will be highly appreciated.
Please make your examples clear enough for me to follow;
