If u wanted to understand more than just how to execute commands.? Here it is ... (pshell)
Introducing P-Shell: A shell that shows its work.
While building it, I explored how Unix processes actually work under the hood.
Some of the things I've implemented:
- Command execution using "fork()" and "execvp()"
- Pipes and output redirection (">", ">>")
- File descriptor manipulation using "dup2()"
- An ":explain" mode that traces shell operations
- Process inspection through "/proc"
- Creating and inspecting a real zombie process, then reaping it using "waitpid()"
One feature I'm particularly interested in is the ability to observe what happens during command execution instead of treating the shell as a black box.
This project has helped me get more hands-on with C programming, Linux processes, and operating-system concepts.
It's still a work in progress, and I plan to keep improving it.

If you're interested in C, Linux, or systems programming, *I'd appreciate it if you checked out the repository and left feedback.
