Topic: shutdown command

Hello all,

where can i find and install "shutdown" command ?

thanks for replies

Given that these little routers don't have much in the way of power management or init system, I'm not sure you can really do a "shutdown" per se, a halt might have to do.

I wondered if you'd have to build a custom busybox to get a halt command, until I checked the source code for busybox's halt command.

All it does is send SIGUSR1 to the init process, i.e. process #1.

This small shell script will do the job:

#!/bin/sh
# halt:  stops the system

kill -USR1 1

Note that this is an immediate halt.

USR2 will similarly reboot the system.

Now if you'll excuse me, I'm going to go power cycle my halted router tongue

heu, i would like to use "shutdown" command to shutdown PCs on my lan, not to shutdown my router...

thanks

The discussion might have continued from here.
