This is the seventh in our series of articles highlighting essential system tools. These are small utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For details of all tools in this series, please check the table in the summary section.
Most of the tools covered in our series to date are text-based software. This time, we’re covering Catfish. It’s a graphical search utility written in Python. Its search is powered by find and locate, with search suggestions provided by Zeitgeist. With the 1.4.6 release, Catfish became part of the Xfce family. Xfce is a lightweight desktop environment. But Catfish works well with other desktop environments like GNOME and KDE.
Installation of Catfish is straightforward with most distributions. The software is found in popular distributions’ repositories.
This is open source software, so you can download the source code, and compile it.
The interface is intentionally lightweight and minimalistic, using only GTK+3. ps_mem reports catfish consumes about 37MB of RAM.
The software can be configured using several command line options.
As you can see, there’s the option to use large icons, thumbnails, perform exact matches, show hidden files, together with fulltext searches.
Features of catfish include:
- polkit integration.
- Fulltext searches i.e. search text within text files.
- Perform operations on multiple files.
- Optional headerbars (enabled by default).
- Support for passwordless sudo.
- Folder filter.
- Image thumbnailer.
- Drag’n’Drop of filenames from application.
- Option to show the sidebar.
- Internationalization support – translations are available for Afrikaans, Basque, Belarusian, Brazilian Portuguese, Bulgarian, Catalan, Chinese (Simplified), Chinese (Traditional), Croatian, Czech, Danish, Dutch, Esperanto, Finnish, French, German, Greek, Icelandic, Italian, Japanese, Kurdish, Lithuanian, Polish, Portuguese, Russian, Serbian, Slovak, Spanish, Swedish, Turkish, and Ukrainian.
Catfish is a well-designed, mature, and functional graphical file search utility. It offers good search performance, good support for themes, and is frugal with resources. Seasoned Linux users will probably prefer using the command-line. But if you’re a recent migrator from Windows, you’ll appreciate the software’s exceptional ability at finding files.
