screen-custom
Fork of GNU screen, with some personal QoL improvements.
If you just got the screen package, it pays to read the file INSTALL. This intro only describes the most common features to get you started. A full description of all features is contained in the source package.
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.
