cd /tmp
list last two files: ls -ltr | tail -2
check if size of any of these two files is 0
if true, then send a mail(can use mailx I suppose) else exit

#! /bin/bash

for file in $(ls -rt | tail -2)
do
    if [ ! -s $file ]
    then
        echo " $file has size 0 ;-) " | mailx -s "This is subject" mailid@domain.com
    fi
done

echo "Non zero file found."
