#!/bin/sh
while read FILE; do cp $FILE ZIP_HOLDER/ ; done < filelist.txt
ls -ltr ZIP_HOLDER/*; sleep 2
zip ZIP_HOLDER.zip ZIP_HOLDER/*
ls -ltr ZIP_HOLDER.zip; sleep 2
FILE="ZIP_HOLDER.zip"
echo "From: malay.khawas@mailaddress.local" > "MESSAGE_FILE"
echo "To: `cat listofmailids.txt`" >> "MESSAGE_FILE"
