LinuxQuestions.org - Works in alias, not in script

I have this alias in my tcsh:

Code:

alias hibernate 'xlock -mode blank &; sleep 2; echo -n mem >! /sys/power/state'

So when I run 'hibernate' the shell runs xlock to lock my desktop, waits 2 seconds then makes the computer hibernate. When the computer is woken up, it is properly locked. Fine.

Now I try to port it to a script:

Quote:

#!/bin/sh

xlock -mode blank &
sleep 2
echo -n mem >! /sys/power/state

It hibernates, but won't lock. If I remove the &, then it locks but won't hibernate immediately. It waits to be unlocked to hibernate.

What am I doing wrong?
