File::Same - Detect which files are the same as a given one.
File::Same uses MD5 sums to decide which files are the same in a given directory, set of directories or set of files. It was originally written to test which files are the same picture in multiple directories or under multiple filenames, but can be generally useful for other systems.
File::Same will use an internal cache, for performance reasons.
File::Same will also be careful not to return $original in the list of matched files.
All of the functions return a list of files that match, with full path expanded.
use strict; use warnings;
my @same1 = File::Same::scan_dirs('sample.txt', ['other', '.']);
my @same2 = File::Same::scan_files('sample.txt', ['ex1.txt', 'ex2.txt']);
my @same3 = File::Same::scan_dir('sample.txt', 'somedir');
Scan a list of files to compare against a given file.
Scan an entire directory to find files the same as this one.
Scan a list of directories to find files the same as this one.
