Description: reboot -- restart the operating system

reboot restarts the hardware and operating system.

Although reboot can be run by the super-user at any time, shutdown is normally used first to warn all users logged in of the impending loss of service. See shutdown for details.

[Eily]: I just wrote a oneliner to solve a (non perl) colleague's problem, and it worked on the first try

1nickt adds gingersnaps to the platter on the sideboard.

[Eily]: what's the point of writing perl if people aren't impressed :P
[sierpinski]: Haha
