This commit modifies the operations.hashSum function by adding an alternate code path. This code path is triggered by passing downloadFlag = True. When activated, rclone will download files from the remote and hash them locally. downloadFlag = False preserves the existing behavior of using the remote to retrieve the hash. This commit modifies HashLister to support the new hashSum method as well as consolidating the roles of HashLister, HashListerBase64, Md5sum, and Sha1sum. The printing of hashes from the function defined in HashLister has been revised to work with --progress. There are light changes to operations.syncFprintf and cmd.startProgress for this. The unit test operations_test.TestHashSums is modified to support this change and test the download functionality. The command functions hashsum, md5sum, sha1sum, and dbhashsum are modified to support this change. A download flag has been added and an output-file flag has been added. The output-file flag writes hashes to a file instead of stdout to avoid the need to redirect stdout.

# rclone hashsum
|
|
|
|
Produces a hashsum file for all the objects in the path.
|
|
|
|
## Synopsis
|
|
|
|
|
|
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.
|
|
|
|
By default, the hash is requested from the remote. If the hash is
|
|
not supported by the remote, no hash will be returned. With the
|
|
download flag, the file will be downloaded from the remote and
|
|
hashed locally enabling any hash for any remote.
|
|
|
|
Run without a hash to see the list of all supported hashes, e.g.
|
|
|
|
$ rclone hashsum
|
|
Supported hashes are:
|
|
* MD5
|
|
* SHA-1
|
|
* DropboxHash
|
|
* QuickXorHash
|
|
|
|
Then
|
|
|
|
$ rclone hashsum MD5 remote:path
|
|
|
|
|
|
```
|
|
rclone hashsum <hash> remote:path [flags]
|
|
```
|
|
|
|
## Options
|
|
|
|
```
|
|
--base64 Output base64 encoded hashsum
|
|
--download Download the file and hash it locally; if this flag is not specified, the hash is requested from the remote
|
|
-h, --help help for hashsum
|
|
--output-file string Output hashsums to a file rather than the terminal
|
|
```
|
|
|
|
See the [global flags page](/flags/) for global options not listed here.
