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.
