Custom Rust Shell

This project is a simple custom shell written in Rust. It provides basic command-line functionality, including:

• Running system commands (e.g., ls, cat, etc.)
• Piping commands using |
• Changing directories with cd
• Viewing and modifying the shell's PATH variable with showpath and addpath
• Exiting the shell with exit

Features

• Cross-platform: Handles path separators for both Windows and Unix-like systems.
• Custom PATH management: Use showpath to display the current PATH, and addpath <path> to append a new directory.
• Basic piping: Supports simple command piping (e.g., ls | grep txt).
• Directory navigation: Use cd <dir> to change the current working directory.

Usage

Run the shell with:

cargo run --bin my_shell

Example commands inside the shell:

my shell > showpath
my shell > addpath C:/My/Custom/Path
my shell > cd C:/Users/YourName
my shell > ls -l | grep .rs
my shell > exit

Notes

• The shell is for educational purposes and demonstrates basic process and environment management in Rust.
• Some advanced shell features (like background jobs, advanced piping, or scripting) are not implemented.
