Re: [beagleboard] How to shut down BBB

[Gerald Coley]

There is a shutdown command on the desktop. You can shut it down from the serial terminal by typing "shutdown".

There is no command "shutdown".

All I found it a power button, but you have to push it for 8sec, then release it after all the LEDs go off. And guess the time it requires to shut itself down.

I think if I unplug it directly, it might create some corrupted date if the OS is writing something at the same time.

The reason I do not have "shutdown" command is that I was not a root user. I guess the onboard powerdown button will do the same when we do not have a terminal access. Is it correct??

Nope. I can't get it supported in software. It should. It can. That is what it is there for. But, the SW folks seem to be mystified by it.

Usually shutdown as regular user is allowed with sudo:
first install sudo
then add "user ALL=NOPASSWD: /sbin/shutdown" with visudo to sudoers
# sudo shutdown -h now
will shutdown without any password

You might prefer to change the suid bit:
chmod a+s /sbin/shutdown (see man chmod)
then
# shutdown -h now
without sudo is sufficiant....
