delete_filter.sh

#!/bin/bash

if [ $# -lt 2 ];then
    echo "usage:$0 deleted_list existed_list"
    exit 1
fi

deleted_list=$1
existed_list=$2

if [ ! -f "$deleted_list" ];then
    echo "$deleted_list is not existed"
    exit 1
fi

if [ ! -f "$existed_list" ];then
    echo "$existed_list is not existed"
    exit 1
fi

while read line
do 
#echo $line
    count=`grep "$line$" $existed_list | wc -l` 
    if [ $count -eq 0 ];then
