tmux

tmux is a terminal multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window. It is useful for running more than one command-line program at the same time. It can also be used to detach processes from their controlling terminals, allowing SSH sessions to remain active without being visible.[2]

Features

tmux includes most features of GNU Screen. It allows users to start a terminal session with clients that are not bound to a specific physical or virtual console; multiple terminal sessions can be created within a single terminal session and then freely rebound from one virtual console to another, and each session can have several connected clients.

Some notable tmux features are:[3]

  • Menus for interactive selection of running sessions, windows or clients
  • Window can be linked to an arbitrary number of sessions[4]
  • vi-like or Emacs command mode (with auto completion) for managing tmux[5]
  • Lack of built-in serial and telnet clients (which some consider bloat for the terminal multiplexer)[3]
  • Easier configuration[6][7]
  • Different command keys—it is not a drop-in replacement for screen, but can be configured to use compatible keybindings
  • Vertical and horizontal Window split support

Adoption

tmux is included in the OpenBSD base system,[8] and is available as a package for many other Unix-like operating systems.[5]

gollark: But the borrow checker makes movement UTTERLY safe.
gollark: The Rust project I mostly recently worked on would, I feel, be apioformically irritating in C. Maybe not C++. I didn't try.
gollark: Imagine ever making mistakes in any circumstance.
gollark: (accidentally)
gollark: Yes, memory leaks are considered safe (but are at least very hard to invoke).
