This manual page documents briefly the
lolcat command.
lolcat is a program that concatenates files, or standard input, to
standard output (like the generic
cat), and adds rainbow coloring to
it.
-
-p X, --spread=X
- Inclination of the rainbow stripes
(character widths per line hight; high values (>1000) give almost
horizonal stripes, low values (0.1) almost vertical ones; default:
3.0).
-
-F X, --freq=X
- Frequency of the rainbow effect.
(low values around 0.0001 give almost monochromous screens; default:
0.1).

- Initial value for the random number generator; 0 means
automatic.
