диспетчер экрана с эмуляцией терминала VT100 / ANSI (screen manager with VT100/ANSI terminal emulation)
GETTING STARTED
Before you begin to use screen you'll need to make sure you have
correctly selected your terminal type, just as you would for any
other termcap/terminfo program. (You can do this by using tset
for example.)
If you're impatient and want to get started without doing a lot
more reading, you should remember this one command: "C-a ?".
Typing these two characters will display a list of the available
screen commands and their bindings. Each keystroke is discussed
in the section "DEFAULT KEY BINDINGS". The manual section
"CUSTOMIZATION" deals with the contents of your .screenrc.
If your terminal is a "true" auto-margin terminal (it doesn't
allow the last position on the screen to be updated without
scrolling the screen) consider using a version of your terminal's
termcap that has automatic margins turned off. This will ensure
an accurate and optimal update of the screen in all
circumstances. Most terminals nowadays have "magic" margins
(automatic margins plus usable last column). This is the VT100
style type and perfectly suited for screen. If all you've got is
a "true" auto-margin terminal screen will be content to use it,
but updating a character put into the last position on the screen
may not be possible until the screen scrolls or the character is
moved into a safe position in some other way. This delay can be
shortened by using a terminal with insert-character capability.
