[ ~derf :: projects :: App::Hashl v1.00 ]

hashl creates a database with partial file hashes. Using it, you can for example leech files off slow FTPs withouth wasting bandwidth on duplicates you already have; or you can keep a list of files on an external database and always tell people what you have and what you don't – and find out which files in a given directory are not on the external disk.

hashl only takes the first few MiB of every file into account, giving it a huge speed advantage at the cost of possible (though highly improbable) false positives. Do not use it for file integrity checks.

For further details on these usecases, please see hashl(1).
