Sneakernet Hash Sharing Toolkit

what is shasharet?

A sneaker net is a "network" where people copy files over media they physically move between computers.

Most people have a different understanding on how to organise files. Traditional tools like rsync only skip existing files if the folder structure is synchronised.

Shasharet makes it possible to quickly hash the files on source and target and decide on what you transfer. If duplicate files are detected, they don't get transferred even if they're in different subfolders. You can compare two database files and get a list of

usage

WORK IN PROGRESS – THIS IS HOW IT SHOULD WORK in v1.0!

shash /path/to/folder – hashes all files in given folder and prints the hashes

shash -f /path/to/database /path/to/folder – stores information about target folder in given file

shash cp /path/to/source /path/to/target – copies all files from source folders which doesn't exist in target

shash rm /path/to/source /path/to/target – deletes all files in target which are present in source

shash diff /path/to/source /path/to/target – compares shash.sqlite files in source and target and shows the differences

shash diff -f /path/to/shash.sqlite /path/to/target – compares files in database with target dir and show differences

shash dupes /path/to/src /path/to/dest – prints duplicate files in src/dest

switches

-f file.sqlite – database file location -o file.txt – output a text file with one file per line, relative to the basedir --fuzzy – fuzzy matching, takes metadata into account --fuzzy-mediainfo=FMT – fuzzy matching based on mediainfo "Inform" format tags --include-filetypes
