The way to do exactly what you are attempting is something like:
until [ -z `ps ax | grep SCRIPT | awk ' { print $2; } '`]
Or you could use:
echo $$ > /var/run/SCRIPT.pid
in SCRIPT and then:
SCRIPT_PID=`cat /var/run/SCRIPT.pid`
until [ -z `ps ax | grep $SCRIPT_PID` ]
Whichever you prefer. The second is probably a little more efficient,
but requires modification to two scripts instead of one.
