Crontab Tutorial - Tips & Shortcuts

*/5 * * * * /command

The above is an example of a command that runs every 5 minutes.
Normally instead if the "*/5" you'd have to type
"5,10,15,20,25,30,35,40,45,50,55" etc...

You can use it to run a program every 5 days, 5 months 5 years etc...

Crontab run one a day at a certain time

[code:1:7a3bd32dfa]0 1 * * * /home/backupguy/[/code:1:7a3bd32dfa]

This will run the script every day at 1AM
