Welcome to thesh, a lightweight custom shell written in C. This project is a minimalist command-line interpreter designed for educational purposes. It demonstrates how to build basic shell functionality, including built-in commands, user input parsing, and system command execution.

• Built-in commands:
  • cd – Change the current working directory
  • help – Display information about the shell
  • exit – Exit the shell
  • echo – Print arguments to the terminal
• Executes external system commands (e.g., ls, pwd, etc.)
• Basic error handling
• Clean and readable codebase

• GCC or any C compiler
• Unix-like environment (Linux, macOS, or WSL)

To compile the shell:

gcc -o thesh main.c builtins.c -Wall
