Suppose larsr and bill have accounts on a machine stella.
Thanks to 'screen' they can easily share a terminal window.
both log in to stella (for instace with ssh).
larsr starts screen
and enables multiuser mode
- CTRL-a :multiuser on
and permit bill to connect
- CTRL-a :acladd bill
Now bill can connect to the screen by typing
- screen -x larsr/
Note the '/'. If larsr has many screens, the screen id is entered after the '/'.
