Tom, I quikcly wrote the following (very basic) sample script of how
to spawn a background job and then display an interactive progress
bar.

==
#!/bin/sh

# example of displaying a progress bar, waiting for a process to
complete

# create a shell script to run in the background (this one simply
sleeps
# for n seconds and then exits)
BGJOB=/tmp/~$$.sh
echo "#!/bin/sh
sleep 20
exit 0" > $BGJOB


# start background process
sh $BGJOB &

# get the process id of the background process
CPID=`jobs -p`

# monitor process
EC=0
i=0
while ( [ $EC -eq 0 ] )
do
# is the process still running?
# (is there less of a hack to do it than the following?)
EC=`ps -p $CPID 1>/dev/null 2>/dev/null;echo $?`

# we need to feed the process bar with data
let i++
echo $i

done | zenity --title "Waiting on Job" --progress --pulsate
--auto-close


echo "Job is done"

# cleanup
[ -f $BGJOB ] && rm $BGJOB

#eof

It should hopefully give you an idea of how to do it on your shell
script.
