- download - check by downloading rather than with hash

- checkFileFs - treat checkFileFs:checkFileRemote as a SUM file with hashes of given type
- checkFileRemote - treat checkFileFs:checkFileRemote as a SUM file with hashes of given type
- oneWay - check one way only, source files must exist on remote
- combined - make a combined report of changes (default false)
- missingOnSrc - report all files missing from the source (default true)
- missingOnDst - report all files missing from the destination (default true)
- match - report all matching files (default false)
- differ - report all non-matching files (default true)

If you supply the download flag, it will download the data from
both remotes and check them against each other on the fly. This can
be useful for remotes that don't support hashes or if you really want
to check all the data.
If you supply the size-only global flag, it will only compare the sizes not
the hashes as well. Use this for a quick check.
If you supply the checkFileHash option with a valid hash name, the
checkFileFs:checkFileRemote must point to a text file in the SUM
format. This treats the checksum file as the source and dstFs as the
destination. Note that srcFs is not used and should not be supplied in
this case.
Returns:
- success - true if no error, false otherwise
- status - textual summary of check, OK or text string
- hashType - hash used in check, may be missing
- combined - array of strings of combined report of changes
- missingOnSrc - array of strings of all files missing from the source
- missingOnDst - array of strings of all files missing from the destination
- match - array of strings of all matching files
- differ - array of strings of all non-matching files

- base64 - output the hashes in base64 rather than hex (boolean)
If you supply the download flag, it will download the data from the
remote and create the hash on the fly. This can be useful for remotes
that don't support the given hash or if you really want to check all
the data.
Note that if you wish to supply a checkfile to check hashes against
the current files then you should use operations/check instead of
operations/hashsum.
Returns:
- hashsum - array of strings of the hashes
- hashType - type of hash used
Example:
$ rclone rc --loopback operations/hashsum fs=bin hashType=MD5 download=true base64=true
{
"hashType": "md5",
"hashsum": [
"WTSVLpuiXyJO_kGzJerRLg== backend-versions.sh",
"v1b_OlWCJO9LtNq3EIKkNQ== bisect-go-rclone.sh",
"VHbmHzHh4taXzgag8BAIKQ== bisect-rclone.sh",
]
}
See the [hashsum](/commands/rclone_hashsum/) command for more information on the above.
