This is not useful commands, but they are funny. Can we do silly things sometimes?
Let’s start from coloring our terminal (you can read how it works here: “How to highlight your output in Bash“). We’ll use util:
Concatenate FILE(s), or standard input, to standard output. With no FILE, or when FILE is -, read standard input.
Probably your distributive doesn’t have it by default. So you can install it:
brew install lolcat
– for MacOS, and for Ubuntu:
apt install lolcat
It’s like the
cat util, but paint output to the colors of rainbow.
It shows text flying in and out in a terminal like as seen in “The Matrix” movie.
But it is better when they are together:
cmatrix | lolcat
