On startup, it executes $SHELL in window 0. 15Then it reads $HOME/.screenrc to learn configuration, keybindings, and 16possibly open more windows. 17 18 C-a ? (help) Show all keybindings. 19 20 C-a c (screen) Create new windows. 21 22 C-a SPACE (next) Advance to next window (with wraparound). 23 24 C-a C-a (other) Toggle between the current and previously 25 displayed windows. 26 27 C-a 0 (select n) Switch to window n=0 ... 9. 28 ... 29 C-a 9 30 31 C-a w (windows) Show a list of window names in the status line. 32 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. 36 37 C-a l (redisplay) Redraw this window. 38 39 C-a W (width) Toggle between 80 & 132 columns mode. 40 41 C-a L (login) Try to toggle the window's utmp-slot. 42 43 C-a z (suspend) Suspend the whole screen session. 44 45 C-a x (lockscreen) Execute /usr/bin/lock, $LOCKCMD or a 46 built-in terminal lock. 47 48 C-a H (log) Log stdout of window n to screenlog.n. 49 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. 54 55 C-a C-] (paste) Output copy buffer to current window's stdin. 56 57 C-a < (readbuf) Read the copy buffer from /tmp/screen-exchange. 58 C-a > (writebuf) Write the copy buffer to /tmp/screen-exchange. 59 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. 63 64 C-a D D (pow_detach) Power detach. Disconnect like C-a d but also 65 kill the parent shell. 66 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). 71 72 C-a : (colon) Online configuration change. 73 74See the man page or TeXinfo manual for many more keybindings and commands. 75 76screen -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 80 name. 81 82screen -R reattaches to a detached session or (if none) creates a new 83 session. 84 85screen -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. 88 89screen -list 90screen -ls 91screen -wipe 92 Show all available sessions and their status. Use -wipe to remove 93 DEAD sessions. 94 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). 98 99screen -h 200 100 Starts a new screen session and sets the number of lines in the scrollback 101 buffer to 200. The default is 100 lines. 102 103
