It’s easy to view yourself as “not a real programmer.” There are programs out there that everyone uses, and it’s easy to put their developers on a pedestal. Although developing large software projects isn’t easy, many times the basic idea of that software is quite simple. Implementing it yourself is a fun way to show that you have what it takes to be a real programmer. So, this is a walkthrough on how I wrote my own simplistic Unix shell in C, in the hopes that it makes other people feel that way too.

The code for the shell described here, dubbed lsh, is available on GitHub.
