mtm – micro terminal multiplexer

mtm stands for the Micro Terminal Multiplexer, a terminal multiplexer. This is a program that allows multiple terminal sessions to run within a single (physical or virtual) terminal session.

mtm divides the screen into multiple virtual terminals. Each virtual terminal is updated and accessed independently. At any given time, exactly one virtual terminal is “focused”, meaning that it receives any typed characters. The currently-focused terminal is indicated by the location of the cursor.

Once inside mtm, things pretty much work like any other terminal. However, mtm lets you split up the terminal into multiple virtual terminals.

At any given moment, exactly one virtual terminal is focused. It is to this terminal that keyboard input is sent. The focused terminal is indicated by the location of the cursor.

Features include:

  • Simplicity – there are only a few commands, two of which are hardly ever used. There are no modes, no dozens of commands, no crazy feature list.
  • Compatibility – emulates a classic ANSI text terminal. That means it should work out of the box on essentially all terminfo/termcap-based systems (even pretty old ones), without needing to install a new termcap entry.
  • Very small size – entire project is around 1000 lines of code.
  • Stable.
  • Different terminal types are supported:
    • mtm – supports all of the features of mtm, but with the default 8 “ANSI” colors only.
    • mtm-256color – this can be used if the mtm terminfo description is installed and the host terminal qsupports 256 or more colors.
    • mtm-noutf – supports everything the mtm terminal type does, but does not advertise UTF8 capability.
