| 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 0.1 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 |
| both tmux and screen), vim and various tools and games in the OpenBSD base |
| system. |
| - A optional status line (enabled by default). |
| |
| And major missing features: |
| |
| - 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. |
| - Status line customisation, beyond presence and colour. |
| - Copy and paste. |
| - Scrollback. |
| - 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. It is possible to |
| emulate some of these but tmux does not do this at present. Known working are |
| 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. |
| |
| For debugging, running tmux with -v or -vv will generate server and client log |
| files in the current directory. |
| |
| Bug reports, feature suggestions and especially code contributions are most |
| welcome. Please email: |

| 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" ;-). |
