HSCAN

Scans recursively a path to match given sha1 checksums. Usefull to find duplicate files, or to find relevant/irrelevant files for which you already have the checksums.

USAGE

hscan -d <PATH> -db <PATH>
-d string
      Directory to scan recursively
-db string
      Directory containing text files with sha1 to search (1 checksum by line)

Examples

You have the file dbpath/sha1.txt :

fed5cdfb1c9b121ea6d042dd54842407df3b4a6b
64725786589f263f0ecc1da55c2bcac7eb18e681
12d81f50767d4e09aa7877da077ad9d1b915d75b

Searching for files having those checksums in the directory test/ :

hscan -d test -db dbpath

# result :
Loading database file "dbpath/sha1.txt"... 3 uniq checksum found in "46.975µs"

Scanning path "tmp"...
  1964 files - 0 unreadable files - 492 dirs - 0 unreadable dirs - 3 matches

RESULT
  sha1tmp.txt                              : 3 matches
  Total                                    : 3 matches
