A Unix shell made at 42 School.
By 0yech and Aisling Fontaine
Minishell consists of recreating a minimalist unix shell with very few external tools and libraries. The project is heavily focused on parsing and handling the prompts properly. It is well known for being one of 42's hardest common core projects. It's also its first group project, which definitely adds some complexity to it for anyone unfamiliar with git or versioning concepts.
Some core features to implement would include parsing, pipes, redirections, signal handling, built-ins and environment management.
To see all the requirements, check en.subject.pdf
This version does not include all bonuses, as we focused on its reliability.
If you're getting into Minishell, sit down with your teammate and do a week or two of research before coding anything. Also, close your file descriptors and don't leak memory.
