NAME

dups3 - Show Duplicate Files

SYNOPSIS

 Usage: dups3 files ...

 dups3 is a fast script for discovering duplicate files.  It achieves
 its efficiency by comparing file digests rather than the file
 contents themselves, the latter being much larger in general.

 The NIST Secure Hash Algorithm 3 (SHA-3) is highly collision
 resistant, meaning that two files with the same SHA-3 digest have
 an almost certain probability of being identical.

 The dups3 script works by computing the SHA3-224 digest of each
 file and looking for matches.  The search can reveal more than
 one set of duplicates, so the output is written as follows:

 match1_file1
	match1_file2
	match1_file3
	etc.

 match2_file1
	match2_file2
	etc.
