This one had me confused for ages:

while read LINE
do
        LINE1="${LINE2}"
        LINE2="${LINE}"
        FILENAME1=`echo ${LINE1} | sed -e "s/@.*$//g"`
        FILENAME2=`echo ${LINE2} | sed -e "s/@.*$//g"`
        if [ "${FILENAME1}" = "${FILENAME2}" ]; then
                cleartool describe -fmt "%d\t%u\t%n%Vn\n%c" ${LINE1}
                cleartool describe -fmt "%d\t%u\t%n%Vn\n%c" ${LINE2}
                echo ${FILENAME1}
                cleartool diff ${LINE1} ${LINE2}
        fi
done < ${OUTPUT}

That will read each line of ${OUTPUT} and put it into ${LINE} each time..
