Description

       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.

Examples

       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
