13 Screen provides you with an ANSI/vt100 terminal emulator, which can multiplex
14 up to 10 pseudo-terminals. On startup, it executes $SHELL in window 0.
15 Then it reads $HOME/.screenrc to learn configuration, keybindings, and
16 possibly open more windows.
18 C-a ? (help) Show all keybindings.
20 C-a c (screen) Create new windows.
22 C-a SPACE (next) Advance to next window (with wraparound).
24 C-a C-a (other) Toggle between the current and previously
27 C-a 0 (select n) Switch to window n=0 ... 9.
31 C-a w (windows) Show a list of window names in the status line.
33 C-a a (meta) Send a literal C-a/C-s/C-q to the
34 C-a s (xoff) process in the window.
35 C-a q (xon) For instance, emacs uses C-a and C-s.
37 C-a l (redisplay) Redraw this window.
39 C-a W (width) Toggle between 80 & 132 columns mode.
41 C-a L (login) Try to toggle the window's utmp-slot.
43 C-a z (suspend) Suspend the whole screen session.
45 C-a x (lockscreen) Execute /usr/bin/lock, $LOCKCMD or a
46 built-in terminal lock.
48 C-a H (log) Log stdout of window n to screenlog.n.
50 C-a C-[ (copy) Start copy mode. Move cursor with h,j,k,l.
51 Set 2 marks with SPACE or y. Abort with ESC.
52 (C-[ is ESC.) Preceeding second mark with
53 an a appends the text to the copy buffer.
55 C-a C-] (paste) Output copy buffer to current window's stdin.
57 C-a < (readbuf) Read the copy buffer from /tmp/screen-exchange.
58 C-a > (writebuf) Write the copy buffer to /tmp/screen-exchange.
60 C-a d (detach) Detach screen. All processes continue and may
61 spool output to their pty's, but screen
62 disconnects from your terminal.
64 C-a D D (pow_detach) Power detach. Disconnect like C-a d but also
65 kill the parent shell.
67 C-a K (kill) Kill a window and send SIGHUP to its process
68 group. Per default this would be C-a C-k,
69 but it is redefined in the demo .screenrc
70 (think of killing a whole line in emacs).
72 C-a : (colon) Online configuration change.
74 See the man page or TeXinfo manual for many more keybindings and commands.
76 screen -r [pid.tty.host|tty.host]
77 Reattach to a specific detached session. The terminal emulator
78 reconfigures according to your $TERMCAP or $TERM settings.
79 When you have multiple screens detached, you must supply the session
82 screen -R reattaches to a detached session or (if none) creates a new
85 screen -d [pid.tty.host|tty.host]
86 Detach a screen session remotely. Has the same effect as typing 'C-a d'
87 on the controlling terminal. 'screen -D' will power-detach.
92 Show all available sessions and their status. Use -wipe to remove
95 If sockets are missing, you may send a SIGCHLD to its 'SCREEN'
96 process and the process will re-establish the socket (think of
97 someone cleaning /tmp thoroughly).
100 Starts a new screen session and sets the number of lines in the scrollback
101 buffer to 200. The default is 100 lines.
