FSearch is a fast file search utility that takes inspiration from the Everything Search Engine. Written in C and based on GTK3, it offers instant search results, advanced search syntax, wildcard and RegEx support, and customizable interface options. Users can also include or exclude specific folders to be indexed, as well as exclude certain files/folders using wildcard expressions. The tool requires GTK 3.18, GLib 2.50, and glibc 2.19 (or musl 1.1.15), among others. Available for various distributions, FSearch aims to provide a performance-driven alternative to existing search utilities on Linux.
