What it is
fzf is a command-line fuzzy finder. It takes a list of lines from stdin, shows interactive search, and returns the selected line. That makes it easy to integrate with shells, editors, Git workflows, and text-producing commands.
The point is universality. It is not only file search; it is an interactive selection layer for files, history, Git branches, processes, ripgrep results, directories, or custom scripts.
What is inside
The repository contains Go code, shell integration, key bindings, a Vim/Neovim plugin, installation docs, display modes, search syntax, and many examples.
A practical flow is to pipe a list into fzf, select a line, and use that result in another command.
Select a file with fzf
This command shows the principle: send files into fzf, select one, then open it.
selected=$(find . -type f | fzf)
$EDITOR "$selected"
Strengths and limits
The strength is Unix-style composition. fzf works well with `find`, `rg`, `git`, `ps`, `kubectl`, and custom scripts.
The limitation is the terminal model. Users need to be comfortable with shells and pipes. More visual navigation often requires configuration.
