Screen linux command

Split screen

Two consoles working together

On console 1

screen -S banan

On console 2

Same user as on console 1

screen -x banan

Annoying flashing

You can do what you want in a terminal-independent way using just your .screenrc

vbell on
vbell_msg ''
termcapinfo *  vb=:
The settings are:

1. first line (you already did this)
2. second line cancels the Wuff, Wuff!
3. third line sets the flash to an empty stringNote that the trailing colon (:) is needed for the termcap syntax used by screen.
