NAME

       tty-clock - a terminal digital clock

SYNOPSIS

       tty-clock [-sSbctrvih] [-C [0-7]] [-f format] [-d delay] [-T tty]

DESCRIPTION

       tty-clock displays a simple digital clock on the terminal. Invoked without options it will
       display the clock on the upper left corner of the screen on the terminal it  was  executed
       from.

COMMANDS

       tty-clock  accepts  a number of runtime keyboard commands, upper and lower case characters
       are treated identically.

       K,J,H,L
              vi-style movement commands to set the  position  of  the  displayed  clock.   These
              commands have no effect when the centered option is set.

       [0-7]  Select a different color for displaying the clock.

       B      Toggles displaying a box around the clock. This option is disabled by default.

       C      Toggle  the  clock's  position  to  centered.   When  set the movement commands are
              disabled.

       R      Set the clock to rebound along the edges of the terminal.

       S      Display seconds.

       T      Switch time output to the 12-hour format.

       Q      Quit.

OPTIONS

       -s     Show seconds.

       -S     Screensaver mode. tty-clock terminates when any key is pressed.

       -b     Show box.

       -c     Set the clock at the center of the terminal

       -C [0-7]
              Set the clock color.

       -t     Set the hour in 12h format.

       -T tty Display the clock on the given tty. tty must be a valid character device  to  which
              the user has rw access permissions.  (See EXAMPLES)

       -r     Do rebound the clock.

       -f format
              Set the date format as described in strftime(3).

       -n     Do not quit the program when the Q key is pressed (or when any key is pressed while
              in Screensaver mode). A signal must be sent to tty-clock in order to terminate  its
              execution. (See EXAMPLES)

       -v     Show tty-clock version.

       -i     Show some info about tty-clock.

       -h     Show usage information.

       -d delay
              Set the delay (in nanoseconds) between two redraws of the clock.

EXAMPLES

       To  invoke  tty-clock  in  screensaver  mode with the clock display set to rebound and the
       update delay set to 1/10th of a second (10 FPS):

              $ tty-clock -Srd 100000000

       The following example arranges for tty-clock to be displayed indefinitely on  one  of  the
       Virtual Terminals on a Linux system at boot time using an inittab(5) entry:

              # /etc/inittab:
              9:2345:respawn:/usr/bin/tty-clock -c -n -T /dev/tty9
