Welcome to tmux!
2007-10-19 20:43:55 +00:00
tmux is a "terminal multiplexer", it enables a number of terminals (or windows)
2007-10-12 17:32:20 +00:00
to be accessed and controlled from a single terminal. tmux is intended to be a
simple, modern, BSD-licensed alternative to programs such as GNU screen.
2007-11-09 16:22:03 +00:00
This 0.1 release should be considered a beta release. It runs on OpenBSD,
FreeBSD and Linux, but has many missing features and is expected to have a good
number of bugs.

tmux consists of a server part and multiple clients. The server is created
when required and runs continuously unless killed by the user. Clients access
the server through a socket in /tmp. Multiple sessions may be created on a
single server and attached to a number of clients. Each session may then
have a number of windows. Commands are available to create, rename and destroy
windows and sessions; to attach and detach sessions from client terminals;
to set configuration options; and to bind and unbind command keys (invoked
preceded by a prefix key, by default ctrl-b). Please see the tmux(1) man page
for further information.
The following is a summary of major features implemented in this version:
- Basic multiplexing, window switching, attaching and detaching.
- Window listing and renaming.
- Key binding.
- Handling of client terminal resize.
- Terminal emulation sufficient to handle most curses applications. Without
known issues are: emacs, irssi, mutt, ncmpc (resize problems are present in
2007-10-19 20:43:55 +00:00
both tmux and screen), vim and various tools and games in the OpenBSD base
system.
2007-10-12 17:32:20 +00:00
- A optional status line (enabled by default).
And major missing features:
2007-10-19 20:43:55 +00:00
- Support for VT100 line drawing characters (they will appear as jklmx, etc).
This is most noticable in ncmpc and in elinks if configured with VT100 frames.
2007-10-12 17:32:20 +00:00
- Status line customisation, beyond presence and colour.
- Copy and paste.
- Scrollback.
- Mouse support.
2007-11-12 20:59:33 +00:00
- No support for programs changing termios(4) settings or other tty(4) ioctls.
2007-10-12 17:32:20 +00:00
A more extensive, but rough, todo list is included in the TODO file.
tmux also depends on several features of the client terminal (TERM), if these
2007-11-09 16:22:03 +00:00
are missing it may refuse to run, or not behave correctly. It is possible to
emulate some of these but tmux does not do this at present. Known working are
2007-11-20 12:09:13 +00:00
TERM=screen (tmux in screen), xterm, xterm-color and rxvt. Note that tmux
(and screen) relies on an AX term capability to detect if the terminal
supports "default" (transparent) foreground and background colours. On OpenBSD,
TERM=xterm and TERM=xterm-color lack this; TERM=rxvt does have it and works fine
at least with the aterm and (naturally) rxvt terminal emulators.
2007-10-12 17:32:20 +00:00
For debugging, running tmux with -v or -vv will generate server and client log
2007-11-09 16:22:03 +00:00
files in the current directory.

Or contact me during UK daytime hours (0900 to 1200 UTC or so) as "NicM" on
freenode or efnet IRC. I sometimes ignore private msgs from people I don't
know, so please mention tmux initially (rather than just saying "hi" ;-).
