Updating From Shell

Is there any difference between F5 & F6 shells? & which should I use for;

sudo zypper dup

?!?

And what do you mean with “F5 & F6 shells”?

The text mode console you get when pressing Ctrl+Alt+F5 or Ctrl+Alt+F6?
Then no, there is no difference.

& which should I use for;

sudo zypper dup

?!?

Doesn’t matter.
