trimstray/the-book-of-secret-knowledge is a highly-starred GitHub repository offering a curated collection of resources for system and network administrators, DevOps, pentesters, and security researchers, though it aims to be useful for everyone. It compiles inspiring lists, manuals, cheatsheets, blogs, hacks, one-liners, and CLI/web tools, organized into main chapters such as CLI Tools, GUI Tools, Systems/Services, Networks, Hacking/Penetration Testing, and Shell One-liners. The project emphasizes quality over quantity, welcoming contributions that are inviting, clear, not tiring, and useful, with an active RSS feed for updates.
