How to run cronjob at 5 hours interval + Linux
In our day to day task, we get request of cron job scheduling
so the script/service will run after certain time interval.
If we want our cronjob (eg. restarting rsyslog service) to
run after every 5 hours, then we can edit crontab with below entries:
1. Edit crontab file, it will edit the crontab file
of root user.
[root@cloud home]# crontab -e
2. Make below entry:
0 */5 * * *
[root@cloud home]# 0 */5 * * * systemctl
restart rsyslog
Or
0 5,10,15,20 * * *
[root@cloud home]# 0 5,10,15,20
* * * systemctl restart rsyslog
3. List crontab file:
[root@cloud home]# crontab -l
Crontab fields:
= * - first * shows minutes [0-59]
= * - second * shows hour [0-23]
= * - third * shows Day of month [1-31]
= * - Fourth * shows month [0-12]
= * - Fifth * shows day of week [0-7]
