create install script for linux

* assumes install script runs in module dir

* Based on
https://stackoverflow.com/questions/48344624/echo-prints-n-differently-between-bin-sh-and-bin-bash
recommended is to use printf, hence used instead of echo.

* Has confirmation qns in beginning
This is to make sure the user has satisfied criterion to run the script
successfully
