"1 crontab
The command to create/edit, list, and remove cron jobs is crontab. If you call it with the -u option, it specifies the name of the user whose crontab is to be tweaked. If this option is not given, crontab examines "your" crontab, i.e., the crontab of the person executing the command. If you are looged in as root and run crontab without -u, then root's crontab is listed/modified/removed. If you are logged in as exampleuser and run crontab without -u, then exampleuser's crontab is listed/modified/removed."
