Short: `Produces an hashsum file for all the objects in the path.`,

Long: `

Produces a hash file for all the objects in the path using the hash

named. The output is in the same format as the standard

md5sum/sha1sum tool.
|
|
|
|
Run without a hash to see the list of supported hashes, eg
|
|
|
|
$ rclone hashsum
|
|
Supported hashes are:
|
|
* MD5
|
|
* SHA-1
|
|
* DropboxHash
|
|
* QuickXorHash
|
|
|
|
Then
|
|
|
|
$ rclone hashsum MD5 remote:path

|
