[gentoo-user] screen / tmux wierdness

[meino.cramer]

Hi,

I have two computers: A small embedded system (beaglebone black)
running Gentoo with commandline interface and my PC running Gentoo
with X and using urxvt for commandline actions.

On both TERM is set to
xterm-256color
and both are using zsh as shell.

On the beaglebone black I cannot use tmux because C-b is not
recognized as command prefix.
On the PC I cannot use screen because C-a is not
recognized as command prefix.

I would like to have the choice on both system what terminal
multiplexer to use.



What can cause this weird behaviour? How can I fix it?



Thank you very much in advance for any help!
Best regards,
mcc

  That's usually controlled by the screenrc file.  Note that you can
have /etc/screenrc and separate ~/.screenrc for each user.  ~/.screenrc
should override /etc/screenrc.  If you don't have ~/.screenrc, screen
will default to /etc/screenrc.  If you want an instance of screen to
start with a nonstandard config file location, use..

screen -c <configfile>

 The setting to change, in whichever file you use, is...

#
# Set C-a as command prefix
escape ^Aa

#
# Set C-b as command prefix
escape ^Bb

Change it to C-a then, I use that with tmux, this is what I have in my
.tmux.conf for that

unbind C-b
set -g prefix C-a

And if you sometimes nest a tmux in another tmux, say you have your
local computer tmux open and you ssh into another box in a tmux
window, then attach a remote tmux session to that window, you can send
the prefix key to the remote tmux using 'C-a a', this means to tmux
'send C-a to the program inside this window', this is also useful if
for some reason you have another program that uses the combination C-a
(or C-b for default configuration).

I would say you only need tmux, it is superior, but that is personal choice.
