What is test-your-sysadmin-skills?

Test Your Sysadmin Skills is a large collection of questions and answers covering topics that Linux system administrators need to know. It contains 284 questions grouped by difficulty and subject area, ranging from introductory warmup questions to advanced topics. The content is organized into chapters covering general Linux knowledge at junior, regular, and senior levels, plus specialized sections on topics like networking, security, system performance, storage, and specific tools. Each question comes with an example answer and often links to additional reading for anyone who wants to go deeper on a topic. Some questions are marked as incomplete, and the project invites contributors to fill in missing answers. The intended use is self-study or interview preparation for people working toward or already in Linux server administration roles. The questions test practical knowledge: things like how the boot process works, how to diagnose a slow system, how to configure firewalls, and how to handle file permissions and user management. Rather than testing memorization of obscure facts, the collection tries to reflect real problem-solving scenarios a working administrator would encounter. The repository is a plain text and Markdown document with no runnable code. It is open source under the MIT license, and contributions through pull requests are welcome.
