Why Use TLDR.sh?

• Saves time: Quickly find relevant command examples without reading through long man pages.
• User-friendly: Ideal for beginners, with simple examples and explanations.
• Up-to-date: TLDR pages are regularly updated with new command examples.
• Cross-platform: Works on Linux, macOS, Windows, and SunOS.
