Input to the script will be

test_run -layout test_vaal -i [ /x/TEST/batch/temp/20070528_ip.txt /x/TEST/batch/temp/20070528__op.txt]

My job is to extract the last occurance of the expression that is from IP_EXPR|Started tp IP_EXPR|Completed

I tried with sed but it gives the following error
sed: -e expression #1, char 40: extra characters after command

Following is my code

IP="test_run -layout test_vaal -i [ /x/TEST/batch/temp/20070528_ip.txt /x/TEST/batch/temp/20070528__op.txt]"
IP_FILE="test.txt"

EXPR=`echo $IP | sed 's/\[//g' | sed 's/\]//g'`
echo "EXPR is : ${EXPR}"

EXTRACTED=`cat $IP_FILE | sed 's/\[//g' | sed 's/\]//g' |sed 's/ /!/g' | sed -n "/${EXPR}/,/${EXPR}/p" `

echo "EXTRACTED is : ${EXTRACTED}"

Can somebody help me out in this
