# htop

Cross-platform TUI (Terminal User Interface) system monitor with multiple implementations.

# Overview

This project implements an interactive system monitor similar to the popular htop utility, with versions for:

Unix/Linux (Rust + ratatui)
Windows (Rust + ratatui)
Windows (Go + tview)

Perfect for learning:

TUI development
System programming
Process management
Cross-platform development

# Quick Start

bash

# Build Unix version (Linux/macOS)
cargo build --release -p htop-rust

# Run
./target/release/htop-unix-rust

# Build Windows Rust version
cargo build --release -p htop-win-rust

# Build Windows Go version
cd htop/win/go && go build -o bin/htop-win-go ./cmd/htop-win-go

# Keyboard Shortcuts

Key	Action
`q`	Quit
`k`	Kill selected process
`/`	Search/filter processes
`s`	Change sort column
`+`/`-`	Adjust refresh interval
`↑`/`↓`	Navigate process list
