Today I learned about the say command in macos. You use it like:

$ say something

It may not seem useful, but I use it when I have long scripts to run...

npm run build && say "build done"

...and It can also be used to do fun things...

say abcdefghijklmnopqrstuvwxyz # The impossible is possible
say dskfjkhadsfhjkasjhkfgjdasgfj
