New page

[http://tmux.sourceforge.net/ Tmux] is a terminal multiplexer: it enables a number of terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.

A lot of people are using [http://www.gnu.org/software/screen/ GNU Screen] to run OpenSimulator but Tmux is offering some good tools to enhance the task.

Tmux is mostly working like Screen except that the default shortcut to run commands is ctrl+b instead of ctrl+a.

A quick crash course is [http://robots.thoughtbot.com/post/2641409235/a-tmux-crash-course available here].

== Installation ==
=== Debian ===
sudo aptitude install tmux
If you would like to use ctrl+a instead of ctrl+b and get some usefull shortcuts, you can use a ~/.tmux.conf file and add inside
# remap prefix to Control + a
set -g prefix C-a
unbind C-b
bind C-a send-prefix

# force a reload of the config file
unbind r
bind r source-file ~/.tmux.conf

# quick pane cycling
unbind ^A
bind ^A select-pane -t :.+

== Running sessions ==
You can start sessions using the syntax :
tmux new -s my_session_name
to detach the session, you can use the shortcut ctrl+b d

Then, you can use the "-t" (target) switch to target a session for a command.
tmux attach -t my_session_name

== Windows and panes ==
=== Windows ===
Tmux has the ability to use "tabs" for the display.
Tabs are called "windows".
You can create a "window" using the shortcut ctrl+b c
Then switch between windows with ctrl+b [0-9]

=== Panes ===
Tmux has the ability to split a window in several "panes".
To split vertically, use the shortcut ctrl+b "
To split horizontally, use the shortcut ctrl+b %
To move the cursor between panes, use the shortcut ctrl+b and arrows keys
If you use the 3 keys at the same time, you can resize the actual pane.

== Sharing sessions ==
Here is the intersting part to use Tmux with OpenSimulator.
The session is shared using a "socket" and the users sharing the session have to be allowed to write in this socket.

=== Prepare the place ===
We will create a group and add all the users sharing the session in this group.
We will create a folder in the /tmp folder to host the socket.
We will give the write authorization to the group on the socket folder.

groupadd tmux-share
addgroup tmux-share myuser
addgroup tmux-share myotheruser
mkdir /tmp/tmux-share
chgrp tmux-share /tmp/tmux-share
chmod -R 2775 /tmp/tmux-share

=== Create the session ===
tmux -S /tmp/tmux-share/1 new-session -s mysession

=== Join the session ===
tmux -S /tmp/tmux-share/1 attach -t mysession

== Send commands to the session ==
This can be usefull to send commands to the sessions using a batch script or anything else.
To do it, you can use a syntax like this :
tmux send-keys -t mysession:1 "ls" C-m
so if you would like to send commands using the socket :
tmux -S /tmp/tmux-share/1 send-keys -t mysession:1 "ls" C-m

== log the output ==
To prevent you losing too much time looking for the answer, here is a working (at least) version of a command to log the output.
tmux -S /tmp/tmux-share/test new -s test1
tmux -S /tmp/tmux-share/test pipe-pane -o -t test1 'cat >> tmux.log'
