Use: "sha1sum remote:path",
|
|
Short: `Produces an sha1sum file for all the objects in the path.`,
|
|
Long: `
|
|
Produces an sha1sum file for all the objects in the path. This
|
|
is in the same format as the standard sha1sum tool produces.
|
|
|
|
By default, the hash is requested from the remote. If SHA-1 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 SHA-1 for any remote.
|
|
|
|
For other algorithms, see the [hashsum](/commands/rclone_hashsum/)
|
|
command. Running ` + "`rclone sha1sum remote:path`" + ` is equivalent
|
|
to running ` + "`rclone hashsum SHA1 remote:path`" + `.
|
|
|
|
This command can also hash data received on standard input (stdin),
|
|
by not passing a remote:path, or by passing a hyphen as remote:path
|
|
when there is data to read (if not, the hyphen will be treated literally,
|
|
as a relative path).
|
|
|
|
This command can also hash data received on STDIN, if not passing
|
|
a remote:path.
