Fuzzy Finder - Linux

In Linux and other Unix-like environments, a fuzzy finder is a command-line tool that helps users quickly search and select items (like files, commands, or options) by typing partial or approximate input. It is especially useful when you can't remember the exact name of a file or command.

🔍 What Does “Fuzzy” Mean?

“Fuzzy” means the tool matches patterns even if the input isn’t exact. For example, typing rdc might match read_config_file.txt because the letters appear in order, even if not consecutively.
