[gentoo-user] OT: bash scripting: implement uninterruptable sleep

[Sascha Lucas]

Hi List,

I have a shell script and want a uninterruptable sleep. /usr/bin/sleep 
itself seems to have its own signal handlers. How is it possible to sleep 
uninterruptable?

#!/bin/bash
trap "echo 'Ctrl+C should not work'" INT

for foo in 1 2 3; do
 	echo $foo
 	sleep 10
done
## end of script

TIA,

Sascha.
