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.

If you want to take searching to the next level you can do so using regular expressions thanks to FSearch’s support of theĀ PCRE (Perl-Compatible Regular Expression) library.

Hi Martin, how do you configure shortcuts for this ?
I see no option for doing so in the drop downs.
I have been using FSearch since it first came on the scene. In fact, the menu was displayed mostly in Spanish back then. I think it may have had one or two English words. It was special then. Only ANGRYSearch compared but it did not have FSearch’s speed.
I keep Catfish on hand for any specialized searching I need to do but if you keep the FSearch database updated it can do it all. Great article. I am glad to see FSearch really come into its own and become a must have search utility. It has earned it.
Nice one Mike. Thanks.
I simply used the terminal commands provided by Martins (no quotation marks; no ‘$’ sign–that is his ‘prompt’)(after typing a command containing “sudo”, one must then type his/her username when prompted)–
“$ sudo add-apt-repository ppa:christian-boxdoerfer/fsearch-daily”
“$ sudo apt update && sudo apt install fsearch-trunk”
The program showed up immediately in Mint’s Menu under ‘Favorites’; then used ‘right-click’ to add to Desktop.
The program is FAST!
Thanks, Martins. Keep up the good work.
sudo command returns an error…
I had the same issue. Make sure you do NOT include the $ at the start of either command and it should work.
That’s right. The $ is not part of the command as it is just an indicator that’s already in your terminal @adelejkruger:disqus
