NAME¶

gdc - grand digital clock (curses)

SYNOPSIS¶

gdc [options] [n]

DESCRIPTION¶

Gdc runs a digital clock made of reverse-video blanks on a terminal screen. If the terminal supports color, the clock is drawn in red. You can make the clock stop, pause or resume by pressing a ``q'', ``s'' or space, respectively.

OPTIONS¶

-d

use terminal's default colors for the background.

-n

redirects input to /dev/null, making it ignore the stop/pause commands. You can still stop it by pressing the interrupt key.

-s

makes digits scroll as they change. When running on a fast display, the program breaks up the scrolling into subsecond repaints, making the operation appear smooth.

-t hh:mm:ss

specify starting time (default is ``now'').

With an optional numeric argument num it stops after num seconds. Normally it runs "forever" (counting down from 2 billion seconds).
