Description
===========

Synchronizes a filesystem directory with objects in a bucket.
Traverses sub-directories copying new and modified files or objects
from the source to the destination and optionally deleting those that
are not present in the source.


Usage
=====

   oci os object sync [OPTIONS]


Required Parameters
===================

-bn, --bucket-name [text]

The name of the bucket.


Optional Parameters
===================

--cache-control [text]

The optional Cache-Control header that defines the caching behavior
value to be returned in GetObject and HeadObject responses. Specifying
values for this header has no effect on Object Storage behavior.
Programs that read the object determine what to do based on the value
provided. For example, you could use this header to identify objects
that require caching restrictions.

--content-disposition [text]

The optional Content-Disposition header that defines presentational
information for the object to be returned in GetObject and HeadObject
responses. Specifying values for this header has no effect on Object
Storage behavior. Programs that read the object determine what to do
based on the value provided. For example, you could use this header to
let users download objects with custom filenames in a browser.

--content-encoding [text]

The optional Content-Encoding header that defines the content encoding
of the object to be returned in GetObject and HeadObject responses.
Specifying values for this header has no effect on Object Storage
behavior. Programs that read the object determine what to do based on
the value provided. For example, you could use this header to
determine what decoding mechanisms need to be applied to obtain the
media-type specified by the Content-Type header of the object.

--content-language [text]

The optional Content-Language header that defines the content language
of the object to be returned in GetObject and HeadObject responses.
Specifying values for this header has no effect on Object Storage
behavior. Programs that read the object determine what to do based on
the value provided. For example, you could use this header to identify
and differentiate objects based on a particular language.

--content-type [text]

The optional Content-Type header that defines the standard MIME type
format of the object to be returned in GetObject and HeadObject
responses. Content type defaults to ‘application/octet-stream’ if not
specified. Specifying values for this header has no effect on Object
Storage behavior. Programs that read the object determine what to do
based on the value provided. For example, you could use this header to
identify and perform special operations on text only objects.

--delete

delete files/objects that exist in the destination but not in the
source. No files or objects are deleted by default.

--dest-dir [text]

Required when not specifying –src-dir. The directory into which
objects in a bucket will be synced as files. This directory will be
created if it does not exist. An object will require downloading if it
does not exist in the local directory or if it exists, either the size
of the object differs from the size of the local file or the last
modified time of the object is newer than the last modified time of
the local file. Objects in Archive tier which have not been restored
will not be downloaded.

--dry-run

Prints the list of files that would be uploaded, downloaded or deleted
without actually performing any actions.

--encryption-key-file [filename]

A file containing the base64-encoded string of the AES-256 encryption
key associated with the object.

--exclude [text]

Only process files which do not match the specified pattern. Patterns
are applied relative to the current directory. This option can be
specified multiple times to match on multiple patterns. Supported
pattern symbols are: 

*: Matches everything

?: Matches any single character

[sequence]: Matches any character in sequence

[!sequence]: Matches any character not in sequence

--from-json [text]

Provide input to this command as a JSON document from a file using the
file://path-to/file syntax.

The "--generate-full-command-json-input" option can be used to
generate a sample json file to be used with this command option. The
key names are pre-populated and match the command option names
(converted to camelCase format, e.g. compartment-id –> compartmentId),
while the values of the keys need to be populated by the user before
using the sample file as an input to this command. For any command
option that accepts multiple values, the value of the key can be a
JSON array.

Options can still be provided on the command line. If an option exists
in both the JSON document and the command line then the command line
specified value will be used.

For examples on usage of this option, please see our “using CLI with
advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Conte
nt/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

--include [text]

Only process files which match the specified pattern. Patterns are
applied relative to the current directory. This option can be
specified multiple times to match on multiple patterns. Supported
pattern symbols are: 

*: Matches everything

?: Matches any single character

[sequence]: Matches any character in sequence

[!sequence]: Matches any character not in sequence

--metadata [text]

Arbitrary string keys and values for user-defined metadata. This will
be applied to all files being uploaded. Must be in JSON format.
Example: ‘{“key1”:”value1”,”key2”:”value2”}’

-ns, --namespace, --namespace-name [text]

The top-level namespace used for the request. If not provided, this
parameter will be obtained internally using a call to ‘oci os ns get’

--no-follow-symlinks

Symbolic links will be ignored while traversing the local filesystem.

--no-multipart

Do not transfer the file in multiple parts. By default, files above
128 MiB will be transferred in multiple parts, then combined.

--parallel-operations-count [integer range]

The number of parallel operations to perform. Decreasing this value
will make the process less resource intensive but it may take longer.
Increasing this value may decrease the time taken, but the process
will consume more system resources and network bandwidth. The maximum
is 1000. [default: 10]

--part-size [integer range]

Part size (in MiB) to use when downloading an object in multiple
parts. The minimum allowable size is 128 MiB.

--prefix [text]

When specified with –src-dir, the files are uploaded as objects with
the specified prefix. When specified with –dest-dir, only objects with
the specified prefix are downloaded but the prefix is not added to the
file names.

--src-dir [text]

Required when not specifying –dest-dir. The directory from which the
files will be synced to a bucket as objects. A local file will require
uploading if the size of the local file is different than the size of
the object, the last modified time of the local file is newer than the
last modified time of the object, or the local file does not exist
under the specified bucket and prefix.

--storage-tier [text]

The storage tier that the objects should be stored in. If not
specified, the objects will be stored in the same storage tier as the
bucket.

Accepted values are:

   Archive, InfrequentAccess, Standard

security policies before trying the examples.
