Important Note on Usage

While these cheat sheets aim to be informative and accurate:

• The commands and configurations provided are for educational and quick reference purposes.
• Some commands, especially those in security-focused cheatsheets (like dorks or Aircrack-ng), can be misused. Always ensure you have explicit authorization before testing or using any potentially disruptive commands on systems or networks you do not own.
• The world of technology is ever-evolving. While efforts are made to keep information current, always cross-reference with official documentation for the latest best practices and command options.
• Users are responsible for their own actions when using information from these cheatsheets.
