The ExampleMe Page, 
for  some "Live" commands.

         

       
You can use every command 
you  see here

   except the one that I - as a regular user - "try" to erase a user's home directory with the command:

 rm -r /home/guest 

         

         As you can see, I don't get out of my home 
dir.

         And I Didn't login as root
