How to Use

These cheat sheets are designed for quick lookup, not linear reading. Bookmark the ones you use most and search within them when you need a specific command or pattern.

Tips:

• Use your browser's find (Ctrl+F / Cmd+F) to search within a cheat sheet
• Code blocks are copy-paste ready -- test in a safe environment first
• "When to use X vs Y" sections help with quick decisions
• Troubleshooting sections cover the most common errors
