Got myself into trouble today - put rhythm box into party mode and I could get it back.
So I was stuck.
I hit ctrl alt del thinking that something like task manager would come up so I could kill rhythm box. Nothing happened so I started hitting all kinds of keys.
Finally I hit ctrl alt fn1 and that got me to a cmd line (I now know that I opened up one of six available 'consoles').
I typed quit - not recognized.
exit - not recognized.
more words - not recognized.
Finally, I typed reboot - needs root. So I did sudo reboot and the box rebooted - everything was OK.
My question is - the next time that I am 'in trouble' - the machine won't respond for whatever reason - and I decide to open up a console, what are the 5 to 10 most important commands that I should learn in order to get myself 'out of trouble?'
I am using raring.
