This article explains how to create the rc.local file using the terminal in Linux

In modern Linux distributions, the rc.local file is not found in the system so one will need to be created in order to start the Elo touch driver on startup. 

The easiest way to create the rc.local file through a linux terminal is the cat command. 

$ cat rc.local

The new file will be created then enter the script provided in Step III.1 of the Installation Instructions:

 #!/bin/sh -e

         /etc/opt/elo-mt-usb/loadEloMultiTouchUSB.sh  
         exit 0 

Finally, save and close the file using CTRL+D or escape using CTRL+C

The finished file will then need to be moved to the '/etc/' directory.
