GNU Screen – full-screen window manager

Last Updated on July 11, 2021

GNU Screen is a terminal multiplexer that runs several separate “screens” on a single physical character-based terminal. Screen prevents a session from “timing out” or disconnecting SSH connections or local terminal emulators.

Each virtual terminal emulates a DEC VT100 plus several ANSI X3.64 and ISO 2022 functions. Screen sessions can be detached and resumed later on a different terminal.

There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows moving text regions between windows.

Features include:

• Configurable input and output translation.
• Serial port support.
• Configurable logging.
• Multi-user support – a window can be displayed on more than one attached displays.
• Altscreen support.
• Split screen support.
• Hardstatus emulation.
• 256 colour support.
• utf8 charset support.
• X11 mouse tracking.
• Input translation.
• Huge number of commands.
• Optional braille support.
