This project teaches us how to create a shell.
It is also the first 42 project that is requiered to be done as a group.
The requiered part of this program is to handle the basics of a shell:
- Commands execution
- Various built-ins
- Input parsing with and without quotes
- Input && output redirections
- Environment management
- Signal handling
We learn how to use different system functions:
- Fork, Pipe, Execve
- Waitpid, Dup2
- Signal
- Chdir, pwd
The program is about parsing and execution. Taking a char* as input, we create an array of tokens, and execute it depending on its contents. Memory allocation and leaks handling was all done with our own C Garbage Collector (featured on my github). https://github.com/willrsq1/Garbage_Collector_C The same system was used to handle file descriptors, allowing us to open as many redirections/use as many pipes as we want.
It was really fun to do ! But so many small options made it tedious in the end.
We also did the bonuses. It was two different parts: wildcards and handling more complex commands.
Wildcards were easy: some parsing/memory manipulation while using opendir.
Handling "&&", "||" and parenthesis was more challenging, but it ended up going great.
Feel free to try it; some additional options are available and can be enabled, just launch "minishell --help". Most of them show how the input is treated: what happens inside the program.
