hash - Calculate file hashes


gsutil hash [-c] [-h] [-m] filename...


Calculate hashes on local files, which can be used to compare with gsutil ls -L output. If a specific hash option is not provided, this command calculates all gsutil-supported hashes for the files.

Note that gsutil automatically performs hash validation when uploading or downloading files, so this command is only needed if you want to write a script that separately checks the hash.

If you calculate a CRC32c hash for files without a precompiled crcmod installation, hashing will be very slow. See the help topic >gsutil help crcmod for details.



Calculate a CRC32c hash for the specified files.


Output hashes in hex format. By default, gsutil uses base64.


Calculate a MD5 hash for the specified files.
