Renames files to its original name based on checksums found in catalog files (SFV or PAR2).
Usage: reverse-checksum-renamer [-i <input>] [-o <output>] <SFV/PAR2-files>
-i input directory
-o output directory
-p show referenced files in par2 or sfv file
(--show-catalog)
-f find PAR2/SFV files and rename them
(--fix-catalog-files)
-c only complete sets
-g group into subdirectories
-v verbose
-d dry run
--degree-of-parallelism <number>
maximum concurrent threads to calculate checksumes of files (0 is number of cores)
--checksum-file
print checksums of a file
-i if omitted the current directory will be the working path
-o if given all renamed files and the correcponding catalog files will be moved to that directory
-f use to find catalog files in all of the input files (determined by header and content)
-g if there are more than one catalog file, all to that catalog corresponding files will be
moved into a single directory below the output directory
-c only move files if all files referenced in the catalog file are found
-d do not move or rename files
-p list all referenced files in the given catalog file
The 'SFV/PAR2-files' argument can be any file or even a '*' wildcard. If the fiule is not a recognised catalog file, it will be ignored.
Consider having a bunch of files, which once have been part of a split archive. Due to a tragic event in the space-time they lost their original names. Fortunately there exists a catalog file which contains the original filenames and a corresponding MD5 or SHA1 hash, which allows us to reconstruct the original filenames by comparing the hashes of the misnamed files to the hashes of the catalog file.
