Introduction to GNU Screen
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 the 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 the user to move text regions between
windows. When screen is called, it creates a single window with a shell in
it (or the specified command) and then gets out of your way so that you can
use the program as you normally would. Then, at any time, you can create new
(full-screen) windows with other programs in them (including more shells),
kill the current window, view a list of the active windows, turn output
logging on and off, copy text between windows, view the scrollback history,
switch between windows, etc. All windows run their programs completely
independent of each other. Programs continue to run when their window is
currently not visible and even when the whole screen session is detached
from the users terminal.
