Name

shutdown — Halt, power-off or reboot the machine

Synopsis

shutdown [OPTIONS...] [now] [WALL...]

Description

shutdown may be used to halt, power-off or reboot the machine.

The first argument should be the string now which however is ignored by this implementation. Optionally, this may be followed by a wall message to be sent to all logged-in users before going down.

Options

The following options are understood:

--help

Prints a short help text and exits.

-H, --halt

Halt the machine.

-P, --poweroff

Power-off the machine (the default).

-r, --reboot

Reboot the machine.

-h

Equivalent to --poweroff, unless --halt is specified.

-k

Don't halt, power-off, reboot, just write wall message.

--no-wall

Don't send wall message before halt, power-off, reboot.

Exit status

On success 0 is returned, a non-zero failure code otherwise.

Notes

This is a legacy command available for compatibility only.
