Download objects from containers.

whole account, omit this and specify --all.
[<object>] Name of object to download. Specify multiple times
for multiple objects. Omit this to download all
objects from the container.
Optional arguments:
-a, --all Indicates that you really want to download
everything in the account.
-m, --marker <marker> Marker to use when starting a container or account
download.
-p, --prefix <prefix> Only download items beginning with <prefix>
-r, --remove-prefix An optional flag for --prefix <prefix>, use this
option to download items without <prefix>
-o, --output <out_file>
For a single file download, stream the output to
<out_file>. Specifying "-" as <out_file> will
redirect to stdout.
-D, --output-dir <out_directory>
An optional directory to which to store objects.
By default, all objects are recreated in the current
directory.
--object-threads <threads>
Number of threads to use for downloading objects.
Default is 10.
--container-threads <threads>
Number of threads to use for downloading containers.
Default is 10.
--no-download Perform download(s), but don't actually write anything
to disk.
-H, --header <header:value>
Adds a customized request header to the query, like
"Range" or "If-Match". This option may be repeated.
Example: --header "content-type:text/plain"
--skip-identical Skip downloading files that are identical on both
sides.
--version-id <version-id>
Download specific version of a versioned object.
--ignore-checksum Turn off checksum validation for downloads.
--no-shuffle By default, when downloading a complete account or
container, download order is randomised in order to
reduce the load on individual drives when multiple
clients are executed simultaneously to download the
same set of objects (e.g. a nightly automated download
script to multiple servers). Enable this option to
submit download jobs to the thread pool in the order
they are listed in the object store.
--ignore-mtime Ignore the 'X-Object-Meta-Mtime' header when
downloading an object. Instead, create atime and mtime
with fresh timestamps.

Generates a temporary URL for a Swift object.
Positional arguments:
<method> An HTTP method to allow for this temporary URL.
Usually 'GET' or 'PUT'.
<time> The amount of time the temporary URL will be
valid. The time can be specified in two ways:
an integer representing the time in seconds or an
ISO 8601 timestamp in a specific format.
If --absolute is passed and time
is an integer, the seconds are intepreted as the Unix
timestamp when the temporary URL will expire. The ISO
8601 timestamp can be specified in one of following
formats:
i) Complete date: YYYY-MM-DD (eg 1997-07-16)
ii) Complete date plus hours, minutes and seconds:
YYYY-MM-DDThh:mm:ss
(eg 1997-07-16T19:20:30)
iii) Complete date plus hours, minutes and seconds with
UTC designator:
YYYY-MM-DDThh:mm:ssZ
(eg 1997-07-16T19:20:30Z)
Please be aware that if you don't provide the UTC
designator (i.e., Z) the timestamp is generated using
your local timezone. If only a date is specified,
the time part used will equal to 00:00:00.
<path> The full path or storage URL to the Swift object.
Example: /v1/AUTH_account/c/o
or: http://saio:8080/v1/AUTH_account/c/o
<key> The secret temporary URL key set on the Swift cluster.
To set a key, run \'swift post -m
"Temp-URL-Key:b3968d0207b54ece87cccc06515a89d4"\'
Optional arguments:
--absolute Interpret the <time> positional argument as a Unix
timestamp rather than a number of seconds in the
future. If an ISO 8601 timestamp is passed for <time>,
this argument is ignored.
--prefix-based If present, a prefix-based temporary URL will be
generated.
--iso8601 If present, the generated temporary URL will contain an
ISO 8601 UTC timestamp instead of a Unix timestamp.
