lolcat - rainbow coloring effect for text console display

lolcat [/options/]/ [/files/] /…

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).

-S */X/, –seed=*/X/

Initial value for the random number generator; 0 means automatic.
(default: 0).

-a, –animate

Fade every line through an animation before printing the next one.

-d */X/, –duration=*/X/

Duration of the animation.
(number of steps before showing next line; default: 12)

-s */X/, –speed=*/X/

Speed of the animation.
(frame rate, ie. number of steps per second; default: 20)

-i, –invert

Inverts the background and foreground colors.

-t, –truecolor

Enables 24-bit truecolor mode.

-f, –force

Force color even when stdout is not a tty.

-v, –version

Shows lolcat version.

-h, –help

Shows options summary.

Typical combinations of lolcat include other programs that generate text:

Large colorful words can be written like this:

  echo "KTHXBAI" | toilet | lolcat

Cows are popular, come in all colors, and tell random epigrams:

  fortune | cowsay | lolcat -a

*cat*(1), *toilet*(1), *fortune*(6), *cowsay*(6)

Very quickly revamped by Mathieu Aubin <mathieu@zeroserieux.com> to include as part of official code repository.
