Tutorial – Write a Shell in C
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.
