如何按计划通过cron重新启动。 Ubuntu 14.04

Question

I have a very simple script that works from the command line.

#!/bin/bash
reboot

When I put a call to execute the script into root users crontab -e using the following format it does not run. It does run the first two commands, just that last one is giving me grief. I have no MTA installed as I do not need it.

*/10 * * * * service jwtpay restart
0 3 * * * bash /root/backup/mongo.backup.s3.sh kickass /root/backup >/dev/null 2>&1
0 */3 * * * bash /root/reboot.sh >/dev/null 2>&1

What am I missing?

Answer 1

Maybe the script is not executable... Since you use root's crontab why call the binary via a script and not the binary itself? Use the full path to the binary. It may vary on your system. Find out where it is with which reboot .

0 */3 * * * /sbin/reboot

Don't forget to restart the cron daemon, after changeing the crontab.
