    Once time or recurring? You can use at or cron.

    In the console window, type man at or man cron to get info on how to use them. In general shutdown is a privileged command, so you will need to create this job as root (sudo).

    You can shutdown the system in many ways.
    Normal linuxes respect init levels (so you would issue init 0).

    Likewise, check man shutdown for the shutdown command use.
    It has its own timer, so if this is a once time, then you can use that.

    You can also specify which users are allowed to shutdown the machine under /etc/shudown.allow, so you won't need root/sudo for that.

    for one time only. I will set new time daily.

    what are the commands I should type in terminal if for example I want to shutdown my PC at 9:00AM and the Desktop User Account is called "Anonymous"?

    sorry for asking to be spoonfed but I'm lost around the terminal part o_O


    OT: When I lock UBUNTU for a few hours and came back... Transmission (bittorrent) stopped running, Empathy on the other hand does not. Why is that? :<

    If you're not comfortable with the command line yet - then do not run any commands you don't know, including shutdown. Please invest time reading and learning about this.

    Why your apps are stopped - there could be a million reasons.
    Have you googled your symptom or checked ubuntu forums?

    shutdown -h 20

    p.s. in this case 20 equals to 20 minutes.
