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 and 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. |
