dotacat

dotacat is meant to be a replacement to lolcat. If you’re not aware, lolcat is a rather silly program which behaves like cat, but produces a colourful, rainbow output.

Why?

Speed!

$ time echo hi | lolcat
real    0m0.422s
user    0m0.393s
sys     0m0.028s

I use lolcat in my .bashrc file, so this amount of time is not ideal for me.

In contrast:

time echo hi | dotacat

real    0m0.045s
user    0m0.030s
sys     0m0.020s

Why the name?

Because Dota is better than LoL (According to people - I play neither)

Installation

If you have cargo installed, just run: cargo install dotacat

If not, head over to the releases page and download the latest release. Then run:

chmod +x dotacat
sudo mv dotacat /usr/local/bin
