EPrints 2.2 Documentation - rehash_documents command



NAME

rehash_documents - Regenerate all the hashes of all documents in the archive.


SYNOPSIS

rehash_documents archiveid [options] [documentid]


DESCRIPTION

This command regenerates the hash values for all documents. This will, by default, create an MD5 hash of all the files in the document in alphabetic order of their path. This value is then stored as a string of hexidecimal characters in the metadata for the document.

This value is automatically re-calculated if more files are uploaded or any files are removed.

It is useful as a quick reliable way of seeing if the document contents has changed. If you generate other formats of a document on-the-fly the MD5 can be useful as part of caching, or you may wish to pass the hashes to a third party to allow you to later verify that an item was in the archive since a given date.

archiveid
The ID of the eprint archive to rehash the documents of.
