Post the problem or question you have in as much detail as you can. Most people will have had experience with cron.

Cron is the scheduling daemon. If your command can run in one line you can enter it directly with crontab -e. If however your trouble is that you are not sure how to write a script you can check out many tutorials and literature.

You can write a bash script by starting the file with

#!/bin/bash

and placing a command on each line. The best place to start in my opinion is The Advanced Bash Scripting Guide. Don't worry it's the guide that's advanced, it does a good job of starting from the start.

EDIT - Space in shabang removed.

Some of us thoroughly enjoy bash scripting. ....Ar....

(Hey bigtomrodney, do you realize you put a space between "/bin" and "/bash"?)

Once you've created the bash script, make it executable (chmod +x script) and use crontab to tell it to execute. I like to keep a local copy of my crontab file, which I save as ~/text/crontab.txt. After I edit it I execute this command:
crontab ~/text/crontab.txt

The file format is fully documented with man 5 crontab.
Be sure to specify the script's whole path.
My crontab.txt file generally looks something like this:

# crontab for Ken Jackson
# Time fields:  minute, hour, day, month, day-of-week (0 or 7 is Sun)
MAILTO=ken
56  6  * * *  $HOME/bin/scriptone
58 22  * * *  $HOME/bin/scripttwo

Default desktop environment for Mandriva is still KDE right? Do it with kcron. It should be in your menu. If not, from the command line:

kdesu kcron

Sounds difficult....any easier method like using xmod + ???
