These systems should have a respective pyqt5-dev-tools package, which should also be installed. The presence of pyrcc5 can be checked with which pyrcc5. Debian based systems need the extra package, and Arch does not. Scanning by filename or content with fuzzy matching to catch similar filenames. -

FDUPES
FDUPES is a program for identifying or deleting duplicate files
FDUPES is a lightweight command-line utility that helps users find and optionally delete duplicate files within specified directories by comparing file contents, which can be extremely useful for cleaning up storage clutter or organizing large collections of files. It works by scanning directories and subdirectories, identifying sets of files with identical content through size and hash comparisons, and then listing them together so users can examine duplicates. Once duplicates are identified, the tool offers interactive deletion options where users can choose which copy to keep and which to remove, or apply flags to automate deletion while preserving a single instance. Because it operates directly on file content rather than just filenames, fdupes can accurately detect true copies and guide cleaning operations in data cleanup or migration tasks. It’s a simple, efficient, and widely used utility on Unix-like systems, appreciated by administrators, developers, and power users. -

SIMILAR
Compares Folders for Same Name and/or Size Files
I developed this application because I was not happy with existing ones. The program analyzes two folders to determine whether they are identical or different by identifying files with the same name and/or size. The resulting list can be saved as a text file. Files with matching names and/or sizes can be deleted, but only those in the second directory will be removed. You can control which files are deleted through the textbox, as only the files displayed there will be deleted. Vary name similarity allows for the identification of files with similar names not exactly the same. Increasing the number of Vary name similarity and Word Size textboxes make the search more restricted. -
