TLDR
The first Unix shell (the Thompson shell) had very limited features, mainly I/O redirection and command pipelines. We'll see how a Linux shell manages to execute commands, loops, and conditional expressions. At the end of this tutorial, we’ll have a basic Linux shell that will not do much for now, but which we'll expand and improve in the next parts. The core part of any Linux shell is the Command Line Interpreter, or CLI. This part serves two purposes: it reads and parses user commands, then executes the parsed commands.via the TL;DR App
