Need help to make Restart script!

[Joacom]

Hello Good Fellows!

I Wonder if anyone has a Script i can use for restart the ubuntu machine every 20 Day.

Thanks in advance!

You should be able to make a crontab entry for shutdown, so something along these lines:

$ sudo vi /etc/crontab

(use whatever editor you prefer but must be sudo/gksudo)

then add an appropriate crontab (http://www.unixgeeks.org/security/newbie/unix/cron-1.html) line, e.g.


0 4 1 * * root shutdown -r +10

This should perform a reboot at 4am on the first day of every month with a 10 minute grace period for anyone who is logged into the machine to save work or abort the reboot.

Making this happen every 20 days is left as an exercise for the reader (http://www.unix.com/shell-programming-scripting/117137-scheduling-command-run-every-3-days-through-cron.html) (who may decide that life's too short and settle for monthly instead ;))

For more information:

$ man shutdown
$ man 5 crontab
