SYNOPSIS
worms |
[-ft ] [-d
delay] [-l
length] [-n
number] |
DESCRIPTION
A UNIX version of the DEC-2136 program “worms”.
The options are as follows:
-d
delay- Specifies a delay, in milliseconds, between each update. This is useful
for fast terminals. Reasonable values are around 20-200. The default is
based on the terminal speed. If the terminal is 9600 baud or slower no
delay is used. Otherwise, the delay is computed via the following formula:
delay = speed / 9600 - 1.
-f
- Makes a “field” for the worm(s) to eat.
-l
length- Specifies a length for each worm; the default is 16.
-n
number- Specifies the number of worms; the default is 3.
-t
- Makes each worm leave a trail behind it.
BUGS
The lower-right-hand character position will not be updated properly on a terminal that wraps at the right margin.
