Ifconfig | grep ' Bcast ' | cut-d b-f 1 >> ip.log
Python mail.py
echo "Master,i has sent you an email.please check!" >>ip.log

Save, exit

Wait 60 minutes after the discovery and did not receive the message.

I crontab instructions in various attempts, check.sh various changes, view crontab log, all kinds of Google found: must be the right!

chmod 777 check.sh
