Crontab Basics
Crontab is a scheduling system for linux. It allows you to schedule scripts and commands. Existing crontab entries are stored in per user files, but are not meant to be edited directly. These files are located as simple text files in the /var/spool/ folder:
|
1 2 3 |
$ cat /var/spool/cron/crontabs/<user> |
Edit Crontab for User
To edit your user simply type:
|
1 2 3 |
crontab -e |
Edit Crontab for Root
If you want to edit for root
|
1 2 3 |
sudo crontab -e |
Edit Crontab for Any User
If you want to edit another user
|
1 2 3 |
sudo crontab -u <user> -e |
List Jobs in Crontab
Like crontab -e, you can list jobs for yourself, root or other users:
- crontab -l
- sudo crontab -l
- sudo crontab -l -u anyuser
