rmdupes is a command-line utility to scan a directory for duplicate files and remove them. The main feature is an option to use a reference directory: all files in the target directory that are duplicates of files in the reference directory will be removed. If no reference directory is given, files in the target directory will be compared against each other.
There is also an option to move files to a backup directory with preserved relative paths.
By default it will not delete any files without confirmation. There are options to perform a dry run, delete without confirmation, automatically select one file to keep from a set of duplicates (oldest, newest, first in alphabetical order). There is also an option for inclusive and exclusive regular expressions to find-type the search by e.g. file extensions or subdirectories.
There is also an option to generate shell scripts to remove the files after inspection.
This is free and open source software.
