Screen

screen - screen manager with VT100/ANSI terminal emulation

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 ISO 6429 (ECMA 48, ANSI X3.64) 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.

Usage

• New Session

$ screen

• Detach Session

Press ctrl + a and d immediately after it.

• List Session(s)

$ screen -ls

• Attach Session

Detached Session can be attached by running screen -r but if multiple session(s) are there, run screen -r <pid.tty.host>.
