What is DUFF: DUplicate File Finder?
DUFF (DUplicate File Finder) is an open source command line utility for identifying duplicate files on Linux and other UNIX-like operating systems. It can help recover disk space by finding copies of the same file in different locations.
DUFF recursively scans directories to build an internal database of file sizes and hash signatures. It then analyzes this data to detect and group together duplicate copies of files. The output is an HTML report that lists the duplicate file groups along with details like file paths and sizes.
As a command line tool, DUFF runs without a graphical interface. It is controlled via command line options and parameters. Key features include:
- Recursively scans directories and subdirectories for duplicates
- Supports inclusion and exclusion of file types
- Filters small files below a configurable size threshold
- Generates a detailed HTML report viewable in web browsers
- Works on Linux and other UNIX-like operating sytems
DUFF is released under the GNU GPL license and available free of charge. It can help find duplicated files wasting disk space and allows the user to selectively delete unneeded copies.
