Long: `

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

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
