Short introduction to screen (Version 3.0.7) jw 7.9.91
provides you with an ansi/vt100 terminal emulator, which can multiplex
up to 10 pseudo-terminals. On startup, it executes $SHELL in window 0.
Then it reads $HOME/.screenrc to learn configuration, keybindings,
and may open more windows.
C-A C Create new windows.
C-A SPACE Advance from window to window (with wraparound)
C-A C-A Toggle between two windows.
C-A 9 Switch to window nr. 0 ... 9.
C-A w Show a list of windows in the Statusline.
C-A a (Think of goto-start-of-line in emacs or tcsh).
C-A s (Think of i-search in emacs).
C-A q Send a literal C-A/C-S/C-Q to the process in the window.
C-A l Redraw this window.
C-A W Toggle between 80 & 132 columns mode.
C-A L Try to toggle the utmp-slot for this window.
C-A A Prompt for a new name for this window. (see C-A w).
C-A z Suspend the whole screen.
C-A x Execute /usr/bin/lock or $LOCKCMD or a builtin terminallock.
C-A C-[ Start copy&paste mode. Move cursor with h,j,k,l. Set 2 marks
with SPACE or y. Abort with ESC. Note that "C-[" is ESC.
NOTE: there is a userdefined amount of scrollback history.
The history buffer is entered, when the cursor hits the top
C-A C-] paste in current window's stdin. see C-A C-[.
C-A > Read or write the copybuffer from/to the exchange file.
Multiple screen users on the same host may thus transfer text.
C-A d Detach screen. All processes continue and may spool output
to their pty's, but screen disconnects from your terminal.
reattach with "screen -r".
C-A D D Power detach. Disconnect like C-A d and kill the parent shell.
C-A K Kill a window and send SIGHUP to its processgroup. Per default
this would be C-A C-k. But it is redefined in the demo .screenrc
(think of killing a whole line in emacs).
C-A :set all Show all keybindings. The above list is not at all complete and
may even be wrong, as keys can be redefined in .screenrc or
with "C-A :bind 'X' keyname [arguments]".
C-A : .... Online configuration change.
Reattach a detached screen session. The terminal emulator reconfigures
according to your $TERMCAP or $TERM settings. '-R' brings up a detached
session or (if none) creates a new session. You should specify a socket
when there you have multiple screens detached.
Detach a screen session from remote. Has the same effect as typing 'C-A d'
on the controlling terminal. '-D' will power-detach.
Show all available sockets. If there are (DEAD???) sockets, you may consider
removing them. If there are sockets missing, you may send a SIGCHLD to its
process 'SCREEN' and the process will re-establish the socket. (think of
someone cleaning /tmp thoroughly).
Starts a new screen session and sets the number of lines in the scrollback
buffer to 200. The default is 50 lines.
