Many of us are familiar with cowsay, "a program which generates an ASCII image of a cow along with a message". You just add your message in quotes after the command like this:

cowsay "hello world"

For the adventurous, you can pipe the output of the fortune command, which generates a random message, into cowsay.

fortune | cowsay

But more adventurous and more fun is to pipe a GROMACS qoute into cowsay. For those unfamiliar with GROMACS, it is a package which allows you to perform molecular dynamic simulations. For those unfamiliar with molecular dynamics, I recommend you read this.

One of the hallmarks of GROMACS is that after every command is run you get a quote. So here is a command which pipes a GROMACS quote into cowsay:

cowsay-gromacs

To get this command, install cowsay and then just download the following repo. Then add this alias to your ./bashrc or ./zsrhc

alias cowsay-gromacs="python3 path/to/repo/main.py | cowsay"

Have fun! 🐄
