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/databackup.sh[/code:1:7a3bd32dfa]
