my changed program

#! /usr/bin/bash
set -x
echo "Enter your friend's name"

read FRIEND
found=no
cat database | while read LINE
do
MATCH= `/users/rdlogche/col_solaris/perl -e $LINE =~ "/^$FRIEND/"`
if [ $MATCH ];then

candidate=$(echo $LINE | cut -d ' ' -f1)
birthday=$(echo $LINE | cut -d ' ' -f2)
found=yes
sleep 1
echo "your friend $candidate 's birthday is on $birthday "
fi

done

if [ $found = no ];then

echo "Sorry no match found"

fi
