Filesystem Searching with Clapgrep and Recoll
Search Party

Clapgrep and Recoll edge out grep for filesystem searches thanks to straightforward graphical user interfaces.
When it comes to searching on Linux, there are various options available to users. The two main players in search operations for, and inside, files are the find [1] and grep [2] command-line tools. While find searches for file name, age, size, and more, grep, which was developed by Unix co-developer Ken Thompson, is a specialist tool that focuses on processing data streams and pattern searching. Regular expressions (regexes) are often used as search patterns. Of course, not everyone is enthralled with the idea of zapping their brain with regexes, which prompted this article on Clapgrep, a variant of grep that has an easily accessible graphical user interface (GUI).
Clapgrep, which only saw the light of day at the start of 2025, has not yet made its way into most distribution archives, although it is available in the Arch Linux AUR. Clapgrep is also available as a Flatpak on Flathub [3]. Clapgrep's source code, which is licensed under GPLv3, is also available on GitHub [4]. However, you will need a very recent platform, such as Fedora Rawhide, to build the application from the source code, making the Flatpak option the approach of choice for the majority of users.
Searching with Clapgrep
Imagine you have a directory with hundreds or even thousands of files. You know that it contains some information that you need, but you have no idea which file the information is hiding in, not to mention which line. This is a typical case for grep or its derivative Ripgrep [5].
