Force a Bash Script to run in Screen

If you create a bash script for a long running process then you may decide its much better, or even essential, that this script is run using screen.

Screen is a utility that allows you to run things in a detachable terminal on the server, so you are not reliant on your own machine maintaining a ssh connection to the server.

A nice trick here is to check if a script is running in screen and die if not

echo "Running Process in separate screen"

if [ -n "$STY" ];
then
        echo 'We are inside screen';
else
        echo "Not in a screen, please run with screen"
        exit 1
