Neste capítulo, vamos concentrar-nos na interação com o Linux no terminal, ou seja, através da shell que expõe uma interface de linha de comandos (CLI). É de importância vital poder utilizar a shell eficazmente para realizar tarefas diárias e, para isso, concentramo-nos aqui na usabilidade.
Primeiro, revemos alguma terminologia e fornecemos uma introdução suave e concisa aos conceitos básicos das conchas. Em seguida, damos uma olhada nos shells modernos e amigáveis ao ser humano, como o Fish shell. Depois, passamos ao tópico de como trabalhar efetivamente na CLI usando um multiplexador de terminal, permitindo que você trabalhe com várias sessões, locais ou remotas. Na última parte deste capítulo, trocamos de marcha e focamos na automatização de tarefas no shell usando scripts, incluindo as melhores práticas para escrever scripts de forma segura, protegida e portátil e também como fazer lint e testar scripts.
