type

Code: Select all

echo poweroff | at 0400

if you want to execute multiple commands, put the commands in a file, one per line, and then type

Code: Select all

at -f /path/to/file 0400

read the man page for at.

If you want to do it on daily basis you can add a cron job with shutdown command

There's no need to write a script for that as posted earlier you can do that using crontab only, here's how,

To add the cron job, do,
crontab -e

then, add,

0 4 * * * reboot
or
0 4 * * * poweroff

(to reboot or shutdown system at 4:00 a.m)

save changes and exit.

chmod +x /etc/cron.daily/sysshutdown

no need to do that.. Just add a cronjob as advised earlier

all cron.daily scripts (on my system) run at 6:25am (see your /etc/crontab for details). you could change the time in /etc/crontab, but then some of the scripts in /etc/cron.daily will run, and the rest won't because your shutdown script ran first.
