Hello! I don't know if anyone can help me, but I want to know what shutdown command starts an immediate shutdown? I know just "shutdown" holds the shutdown for a minute until everyone logs out, but what is the command for immediate shutdown? Thanks!

Try:
init 0

OR
shutdown -h now

If it's really SCO Unix there is no way to bypass the grace period by means of a shutdown flag.

You must use

/etc/haltsys

instead.

Please be aware that "haltsys" does not terminate any user processes gracefully, it halts the processor and just takes care not to corrupt filesystems.

I'd really suggest using shutdown. What's wrong with that 1 minute wait time?

You can run "shutdown -y" to bypass the confirmation prompt.

There isn't a problem really, I was just wondering if there was a way to avoid the 1 minute because everyone who uses that system is already out of the system whenever I need to shut it down so it is just unnecessary really.

"-g0" works on some sco versions. take a look at the man page

you should be able to kill init as well, but i don't really know which signal would initiate a clean shutdown
"kill -9 1" should be VERY efficient though

I couldn't get the immediate shutdown I wanted, but "shutdown -y" got me closest
