[colug-432] scripting

[Vince Herried]

Sigh, google is my friend.
I discovered jobs -p
Whee, that makes it much easier.
I think I have it

#!/bin/bash
sleep 50 &
sleep 50 &
sleep 50 &
sleep 50 &

# now wait
echo -n ' waiting '
for job in `jobs -p` ; do

        echo -n '*'
        sleep 10
done
echo done
