Tmux

(Terminal Multiplexer)

Why Tmux?

  • Mouse free
  • Cross Plantform
  • Sever/Client
  • Just Shell Commands

Pronunciation

  • Terminal MUlitipleXer
  • Tee Mucks

The correct pronunciation of "tmux" is a matter of some dispute in my office. Many avoid the issue by installing screen. @reddit

Tmux VS GNU Screen

+++

tmux

Pros

  • Can send keys to other panes, kind of like an IDE
  • Easy keybindings -- with the right config, you'll feel at home from Vim or Screen
  • Vim-ish and Emacs-ish bindings built-in
  • Good layout management, a lot like a tiling window manager
  • Unicode seems to Just Work with modern terminals
  • Some terminal issues fixed with TERM=tmux

+++

Cons

  • Slow -- unsure why, but keystrokes seem laggy No more issues with slowness
  • Multiplexing forces the whole session width and height to the smallest attached terminal
  • Has crashed multiple times on Mac OS X, losing the entire session(happened to me)
  • Has failed on Linux after upgrade, where I couldn't reconnect to my old session

+++

GNU Screen

Pros

  • Extremely stable (v1.0 was in 1987)
  • Some terminal issues fixed with TERM=screen
  • Emacs-ish bindings built in
  • Easy to move and control horizontal panes
  • When multiplexing, any attached terminal can resize a pane

+++

Cons

  • No vertical splits without patch (except on Ubuntu)
  • Pane splits are lost when detaching
  • Getting Unicode to work takes a little finesse and determination
  • Crazy status line configuration
