[SOLVED] Crontab and SHUTDOWN

Hello Linux fans

I wish for my desktop computer running Linux Mint 18.1 to shut down at 10:30PM every evening. I have tried several combination of commands including the following

30 22 * * * /sbin/shutdown -h now

The thing never shuts down as expected.

Shutdown command needs root privs and you made crontab entry as regular user?

Exactly!. I just tried it by doing

sudo crontab -e

and enter the command in there and worked as expected. It works so well that upon restart linux mint does a file system check.
Is this normal?

Depends on a distro and on init system. In your case, it should be ok if it does not run full check. For more explanation, perhaps you would like to read this: https://askubuntu.com/questions/3831...every-bootup..

Hello

I found that by removing the now shuts downs more gracefully and not presented with a file system check on restart
