fdf is a high performance command line file finder written in Rust.
It’s designed as a lightweight alternative to tools such as fd and find, with an emphasis on fast directory traversal, regex and glob based searching, and POSIX platform support. The project uses low level filesystem optimisations, parallel traversal, and direct system interfaces where available.
This is free and open source software.
Key Features
- Searches files and directories using regular expressions, glob patterns, or fixed strings.
- Supports filters for extensions, file type, file size, modification time, depth, and full path matching.
- Includes multi-threaded traversal with configurable thread count.
- Can respect or ignore .gitignore rules during searches.
- Offers options for hidden files, symlink following, filesystem boundaries, and sorted output.
- Provides null terminated output for use with tools such as xargs.
- Can execute a command once per search result using the exec option.
- Generates shell completions for bash, zsh, fish, PowerShell, and elvish.
- Cross-platform support – runs under Linux, macOS, FreeBSD, NetBSD, OpenBSD, Solaris, Illumos, Android, and 32-bit Linux to varying levels.
