Crontab
(Redirected from Crontab daily script)
To run a script periodically you have to register the script to your CRONTAB.
On old Linux versions you can edit the crontab directly ; while on modern one you should put your script inside a specific folder.
Crontab manual edition (old)
crontab -e
Just add some new entry like:
# m h dom mon dow command
0 2 * * * /root/bin/daily_backup > /root/logs/backup_$(date +\%Y\%m\%d).log
Crontab manual edition (new)
Instead of editing the cron, just put your script in the right folder:
- /etc/cron.hourly
- /etc/cron.daily
- /etc/cron.weekly
- /etc/cron.monthly
All scripts must belong to root:root and have the 755 permissions.
!!! NOTE !!!
You must NOT put a '.' instead your filename! See: http://askubuntu.com/questions/502592/ubuntu-14-04-not-running-bash-scripts-in-etc-cron-daily
- /etc/daily/vehco-cron.sh <<< KO - it will NOT run
- /etc/daily/vehco-cron <<< OK
