- How is tmux different from GNU screen? What else does it offer?
tmux offers several advantages over screen:
- a clearly-defined client-server model: windows are independent entities which may be attached simultaneously to multiple sessions and viewed from multiple clients (terminals), as well as moved freely between sessions within the same tmux server;
- a consistent, well-documented command interface, with the same syntax whether used interactively, as a key binding, or from the shell;
- easily scriptable from the shell;
- multiple paste buffers;
- choice of vi or emacs key layouts;
- an option to limit the window size;
- a more usable status line syntax, with the ability to display the first line of output of a specific command;
- a cleaner, modern, easily extended, BSD-licensed codebase.
There are still a few features screen includes that tmux omits:
- builtin serial and telnet support; this is bloat and is unlikely to be added to tmux;
- wider platform support, for example IRIX and HP-UX, and for odd terminals.
