[prog] bash script - mac address compare and send email

[Chris Henderson]

I'm trying to write a script that will compare MAC address and send
out an email. But it's not working as expected. I have tried both
"-eq" and "==" - but guess the problem is somewhere else. I want to
run this program in the background (with &)

Thanks for any help.

#!/bin/bash

set -x

MAC_AS_READ_FROM_TSHARK=$(tshark -i eth0 -n port 68 -R 'bootp.type ==
2' -o column.format:'"Source MAC","%hs"')

MAC1="00:1F:32:6D:BB"

if [ "$MAC_AS_READ_FROM_TSHARK" -eq "$MAC1" ]; then
            echo "foo" | mail -s "foo" foo at bar
fi
