cheat

cheat is a command-line tool that allows you to create and view interactive cheatsheets directly from your terminal. It was specifically designed to help *nix system administrators remember command options for tools they use frequently but not often enough to memorize completely. The classic example is the tar command - instead of searching Google every time you need to extract or create archives, you can simply run 'cheat tar' to get a quick reference.

The tool supports both viewing existing cheatsheets and creating your own custom ones. You can organize cheatsheets in nested directories, tag them for easy categorization, and search through them using keywords or regular expressions. Cheatsheets are stored as plain-text files with optional YAML frontmatter for metadata like syntax highlighting and tags.

cheat is particularly valuable for DevOps engineers, system administrators, and developers who work with many different command-line tools. It supports multiple "cheatpaths" so you can maintain separate collections - for example, community-sourced cheatsheets alongside your personal ones. The tool also includes advanced features like shell autocompletion, fzf integration for fuzzy finding, and directory-scoped cheatsheets that can be associated with specific projects or directories on your filesystem.
