Try this .. I made some modification ..

#!/usr/bin/sh
echo "pid= \c"
read my_pid

for PID in `ps -ef|sed 's/^ *//g'|grep -v \^UID|awk '{print $2}'`
do
if [ $my_pid -eq $PID ]
then
echo "WE FOUND $my_pid IS $PID"
fi
done

The "ps -ef" is first filtered by removing spaces from begining of each line. Then pass that to "grep -v \^UID" to take away the first line starting with UID and then print out 2nd field which is the UID.
