[NTLUG:Discuss] Simple way to repeat command every 'x' seconds

[Fred James]

#! /bin/bash
#   doforever.sh
if test $# -eq 1
then
    Pause=$1
else
    Pause=20
fi
while test 1
do
    du - H -s
    sleep $Pause
done
exit

Then either of these could be used:
#> ./doforever.sh
#> ./doforever.sh 30
I don't know if you would want to put that in the background, and I 
believe that it would terminate when your shell did.
