renfnv This renames a file to the base32-encoded 64-bit FNV-1a hash of the file's contents. The extension is preserved. This was motivated by a desire to normalise names for photographs. Usage: renfnv [-fhlnv] files... -f force overwriting of files when there is a collision. -h print this help message. -l list changed files. -n Perform a dry run: don't actually move files. -v Print all files as they are processed. If both -v and -l are specified, it will behave as if only -v was specified.
