NAME¶

gdc - grand digital clock using curses

SYNOPSIS¶

gdc [-dns] [-t hh:mm:ss] [count]

DESCRIPTION¶

gdc uses curses to display a clock on the terminal. It constructs the digits from reverse-video blank characters. If the terminal type supports color, the digits are drawn in red. Make the clock stop, pause, or resume by typing “q”, “s”, or space, respectively.

Given a numeric operand, the clock stops after count seconds. Normally, gdc runs “forever” (at least 2 billion seconds).

OPTIONS¶

-d

uses the terminal's default background color.

-n

reads input from /dev/null, making gdc ignore the stop and pause commands. You can still stop it with a terminal interrupt.

-s

scrolls the digits up as they change. When running on a fast display, the program breaks up the scrolling into sub-second redraws, making the operation appear smooth.

-t hh:mm:ss

uses the specified time instead of the current time.
