This is a project where I build a Linux shell using the C language. I have referenced @MIMA's stories on HackerNoon for the same. I intend to gain more knowledge about Operating Systems from this and some other projects, most of which will be from this repository. This shell is called "wish" because the original project which inspired this was also called so.
There are two branches in this project. The master branch contains a simple command-line interpreter(cli) containing a parser and an executor, an abstract syntax tree (AST) and a symbol table. It will run simple commands like "ls" or the built-in dump utility but won't run other utilities like "cd" and "fg". The other branch, titles "more-comprehensive-shell" builds upon the simple shell in the master branch and adds in facilities like tokenizer and whatnot, resulting in a complete shell. However, I have been unable to get it to work as of now, mainly because I started with my first job (yayy), probably the reason why it is in a separate branch for now. This branch is still a good source to refer things and hence will stay up for now. I will again remind you here that the branch won't work and is currently for reference only.
This project, however frustrating it might have been, was a great exercise. This project is for learning purposes only, and was started mainly because I was free for a couple of months after my undergraduate degree was over.
