#!/bin/bash

for i in {0..19}
do
sleep 60 &

while ($((ps au | grep sleep | wc -l)) > 9)
do
sleep 2
done

done

sorry the subject of the email should be "refrain using too many

above one not working, complained:

.sh: line 8: ps au | grep sleep | wc -l: syntax error in expression
(error token is "au | grep sleep | wc -l")
