Screen 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
possibly open more windows.
C-a ? (help) Show all keybindings.
C-a c (screen) Create new windows.
C-a SPACE (next) Advance to next window (with wraparound).
C-a C-a (other) Toggle between the current and previously
displayed windows.
C-a 0 (select n) Switch to window n=0 ... 9.
...
C-a 9
C-a w (windows) Show a list of window names in the status line.
C-a a (meta) Send a literal C-a/C-s/C-q to the
C-a s (xoff) process in the window.
C-a q (xon) For instance, emacs uses C-a and C-s.
C-a l (redisplay) Redraw this window.
C-a W (width) Toggle between 80 & 132 columns mode.
C-a L (login) Try to toggle the window's utmp-slot.
C-a z (suspend) Suspend the whole screen session.
C-a x (lockscreen) Execute /usr/bin/lock, $LOCKCMD or a
built-in terminal lock.
C-a H (log) Log stdout of window n to screenlog.n.
C-a C-[ (copy) Start copy mode. Move cursor with h,j,k,l.
Set 2 marks with SPACE or y. Abort with ESC.
(C-[ is ESC.) Preceeding second mark with
an a appends the text to the copy buffer.
C-a C-] (paste) Output copy buffer to current window's stdin.
C-a < (readbuf) Read the copy buffer from /tmp/screen-exchange.
C-a > (writebuf) Write the copy buffer to /tmp/screen-exchange.
C-a d (detach) Detach screen. All processes continue and may
spool output to their pty's, but screen
disconnects from your terminal.
C-a D D (pow_detach) Power detach. Disconnect like C-a d but also
kill the parent shell.
C-a K (kill) Kill a window and send SIGHUP to its process
group. 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 : (colon) Online configuration change.
See the man page or TeXinfo manual for many more keybindings and commands.
screen -r [pid.tty.host|tty.host]
Reattach to a specific detached session. The terminal emulator
reconfigures according to your $TERMCAP or $TERM settings.
When you have multiple screens detached, you must supply the session
name.
screen -R reattaches to a detached session or (if none) creates a new
session.
screen -d [pid.tty.host|tty.host]
Detach a screen session remotely. Has the same effect as typing 'C-a d'
on the controlling terminal. 'screen -D' will power-detach.
screen -list
screen -ls
screen -wipe
Show all available sessions and their status. Use -wipe to remove
DEAD sessions.
If sockets are missing, you may send a SIGCHLD to its 'SCREEN'
process and the process will re-establish the socket (think of
someone cleaning /tmp thoroughly).
screen -h 200
Starts a new screen session and sets the number of lines in the scrollback
buffer to 200. The default is 100 lines.
