Welcome to tmux!
|
|
|
|
tmux is a "terminal multiplexer", it enables a number of terminals (or windows)
|
|
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.
|
|
|
|
This 0.6 release runs on OpenBSD, FreeBSD, Linux and OS X and may still run on
|
|
Solaris (although it hasn't been tested in a while). It is usable, although
|
|
there remain a number of missing features and some remaining bugs are expected.
|
|
|
|
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 and windows may be linked to a number of sessions. 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
|
|
both tmux and screen), vim and various tools and games in the OpenBSD base
|
|
system.
|
|
- A optional status line (enabled by default).
|
|
- Window history and copy and paste.
|
|
- Support for VT100 line drawing characters.
|
|
- A large command set.
|
|
- Vertical window splitting.
|
|
- Automatic server locking on inactivity.
|
|
- A configuration file.
|
|
|
|
And major missing features:
|
|
|
|
- Proper mouse support.
|
|
- No support for programs changing termios(4) settings or other tty(4) ioctls.
|
|
|
|
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
|
|
are missing it may refuse to run, or not behave correctly. Known working are
|
|
TERM=screen (tmux in screen), xterm, xterm-color and rxvt. Note that TERM=xterm
|
|
does not support colour on OpenBSD. screen ignores this, tmux does not: use
|
|
xterm-color or rxvt for colour.
|
|
|
|
tmux supports UTF-8. To use it, the utf8 option must be set on each window;
|
|
this may be turned on for all windows by setting it as a global option, see
|
|
tmux(1) and the FAQ file. In addition, when starting tmux or attaching to an
|
|
existing session from a UTF-8-capable terminal, the -u flag must be specified.
|
|
|
|
There are the following known issues:
|
|
|
|
- cons25 on the FreeBSD console doesn't support scroll region (cs) (or lies
|
|
about support, I'm not totally clear which). This is a pity but emulating cs
|
|
is nontrivial and as most modern vt220-based software terminals support it,
|
|
currently there are better things to work one. Diffs or ideas how to cleanly
|
|
emulate cs are welcome.
|
|
|
|
For debugging, running tmux with -v or -vv will generate server and client log
|
|
files in the current directory.
