01 · Problem
What made this interesting
Implementing a shell requires parsing complex command syntax with pipes and redirections, managing child processes, and handling signals — all while maintaining POSIX compliance.
02 · Approach
How I solved it
Built a token-based parser for command syntax, implemented pipe-based inter-process communication with fork/exec, and handled built-in commands and signal management within the shell process.
03 · Result
What came out of it
A functional Unix shell supporting piped commands, environment variable expansion, signal handling, and built-in utilities.
