fdupes has no configuration options other than optional command-line parameters.
It’s worth investigating these parameters. The available options are shown with
fdupes -h
fdupes can be compiled for other operating systems besides Linux. We regularly use this tool on NetBSD and FreeBSD.
Features include:
- Support for 64-bit file offsets on 32-bit systems.
- Sorts duplicates (old to new) for consistent order when listing or deleting duplicate files.
- Options include:
- nohidden – excludes hidden files from consideration.
- permissions – with this option, fdupes doesn’t consider files with different owner/group or permission bits as duplicates.
- order – order files according to mtime or by filename.
- reverse – this option reverses the order while sorting.
- immediate – deletes duplicates as they are found without grouping into sets.
- summarize – summarizes duplicate files information.
- recurse – follows subdirectories found.
- noprompt – when used together with –delete, it preserves the first file in each set of duplicates and delete the others without prompting the user.
