Quando você digita um **comando** no terminal, o sistema operacional **procura** o programa em **cada um dos diretórios** listados na variável de ambiente `PATH`.

Por exemplo, quando você digita `python` no terminal, o sistema operacional procura um programa chamado `python` no **primeiro diretório** dessa lista.

E se você clicar, verá um pequeno formulário de autorização para digitar um `username` e um `password` (e outros campos opcionais):

Não importa o que você digite no formulário, ainda não vai funcionar. Mas nós vamos chegar lá.
