Finding out my rstudio server version on my ubuntu

Ian mentioned the rstudio-server and rstudio-server-version commands should be run from your shell.

It would give a result something like this:

username@servername:~/projects/myRproj$ rstudio-server
$Usage: rstudio-server {status|start|stop|restart|test-config|verify-installation|

username@servername:~/projects/myRproj$ rstudio-server version
1.1.442 (Professional)

You mentioned that you're just getting some AWS instances up and running for a classroom, is that right?
Can you reset it and start anew?
