FSearch – A Speedy Standalone Search Utility for Linux

FSearch Search Tool for Linux
Written by Divine Okoi

FSearch is a GTK+3, open-source, performance-focused search utility for GNU/Linux and Unix-like Operating Systems. It is inspired by Everything Search Engine so it instantly locates files and folders by filename and it is written in C so it boasts amazing speeds – a feature its users love about it the most.

It features a modern, customizable GUI with toolbars and a responsive, themeable app window.

What enables the speed of this search utility is its ability to quickly index all the files on your computer. That way, it is able to suggest files from any location as you type letters into its search field.

The results appear in the form of a list and you can sort them by filename, path, size, or modification time. You can decide to open the file using your default app or in the file manager, or you can copy the file (or directory) path to your clipboard.
