worms
is 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 20.
-f
- Makes a “field” for the worm(s) to eat.
-l
length
- Specifies the length of each worm; the default is
16, the minimum is 2.
-n
number
- Specifies the number of worms; the default is 3.
There must be at least one.
-S
seed
- Provide an integer seed for the random number
generator. Specifying zero (0, the default) causes a random seed to be
used.
-t
- Makes each worm leave a trail behind it.
The maximum length, and
number, of worms depends upon the screen size, though
the length can never exceed 1024. If the screen is
particularly small, even the defaults for those may be too large. Screens
with less than 3 rows or columns cannot be handled, nor can ones with
insufficient total space.
