Linux Shell Scripting Cookbook - Third Edition

How to do it...

To run an graphical application on a remote server, you need to set the $DISPLAY variable to force the application to connect to the X server on your local machine:

ssh user@host "export DISPLAY=:0 ; command1; command2""" 

This will launch the graphical output on the remote machine.

If you want to show the graphical output on your local machine, use SSH's X11 forwarding option:

ssh -X user@host "command1; command2" 

This will run the commands on the remote machine, but it will display graphics on your machine.
