    ripgrep

    ripgrep

    Regex pattern directory search tool that respects your .gitignore

    ripgrep is a line-oriented search tool that actively searches the directory you're currently in for a regex pattern. By default, ripgrep will ignore your .gitignore and skip hidden files or directories and binary files automatically. ripgrep has first class support on Windows, macOS and Linux, with binary downloads available for every release. ripgrep is similar to other popular search tools like The Silver Searcher, ack and grep. ripgrep supports arbitrary input preprocessing filters which could be PDF text extraction, less supported decompression, decrypting, automatic encoding detection and so on. In other words, use ripgrep if you like speed, filtering by default, fewer bugs and Unicode support.

    FSearch

    FSearch

    A fast file search utility for Unix-like systems based on GTK3

    FSearch is a blazing-fast file search utility for Linux inspired by Windows’ Everything Search Engine, built to allow users to locate files and directories instantly by name rather than content. It achieves its high performance by indexing the filesystem and updating that index in real time, so as you create, rename, or delete files the results stay up to date without noticeable lag. The intuitive user interface supports incremental search — where results filter as you type — plus features like regular expressions, case-sensitivity options, and customizable indexing scopes, making it both powerful and accessible. Designed with GTK and written in C, it integrates nicely with desktop environments like GNOME, XFCE, and Cinnamon while still being lightweight and resource-efficient. Developers and power users appreciate FSearch for dramatically reducing the time it takes to find files compared to traditional search tools, especially on large partitions.

    fd

    fd

    A simple, fast and user-friendly alternative to 'find'

    fd is a program to find entries in your filesytem. It is a simple, fast and user-friendly alternative to find. While it does not aim to support all of find's powerful functionality, it provides sensible (opinionated) defaults for a majority of use cases. First, to get an overview of all available command line options, you can either run fd -h for a concise help message or fd --help for a more detailed version. fd is designed to find entries in your filesystem. The most basic search you can perform is to run fd with a single argument: the search pattern. Instead of just showing the search results, you often want to do something with them. fd provides two ways to execute external commands for each of your search results: the -x/--exec option runs an external command for each of the search results (in parallel), or the -X/--exec-batch option launches the external command once, with all search results as arguments.

    fzf

    fzf

    A command-line fuzzy finder

    fzf is a general-purpose command-line fuzzy finder. It's an interactive Unix filter for command-line that can be used with any list; files, command history, processes, hostnames, bookmarks, git commits, etc. fzf will launch an interactive finder, read the list from STDIN, and write the selected item to STDOUT. Without STDIN pipe, fzf will use find command to fetch the list of files excluding hidden ones. (You can override the default command with FZF_DEFAULT_COMMAND). fzf by default starts in fullscreen mode, but you can make it start below the cursor with the height option. Unless otherwise specified, fzf starts in "extended-search mode" where you can type in multiple search terms delimited by spaces. Fuzzy completion for files and directories can be triggered if the word before the cursor ends with the trigger sequence, which is by default **. Fuzzy completion for PIDs is provided for the kill command. In this case, there is no trigger sequence.

    Fuse.js

    Fuse.js

    Lightweight fuzzy-search, in JavaScript

    Fuse.js is a powerful, lightweight fuzzy-search library, with zero dependencies. Generally speaking, fuzzy searching (more formally known as approximate string matching) is the technique of finding strings that are approximately equal to a given pattern (rather than exactly). It might not make sense for every situation, but can be ideal depending on your search requirements. For example, qhen you want client-side fuzzy searching of small to moderately large data sets. Also, when you can't justify setting up a dedicated backend simply to handle search. ElasticSearch or Algolia, although both great services, may be overkill for your particular use cases. You can access all options above via Fuse.config. This is useful if you want to override default options for all Fuse instances. Fuse.js supports logical query operators. These operators are used for filtering the data and getting precise results based on the given conditions.
