Multi-screen window manager
Screen is a full-screen window manager that multiplexes a physical terminal between several processes typically interactive shells. Each virtual terminal provides the functions of a DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 ISO 6429 and ISO 2022 standards e.g. insert/delete line and support for multiple character sets. There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows moving text regions between windows.
