bulk-delete-versions

Description

Deletes all object versions in a bucket which match the provided criteria.

Usage

oci os object bulk-delete-versions [OPTIONS]

Required Parameters

-bn, --bucket-name [text]

The name of the bucket.

Optional Parameters

--delimiter [text]

When this parameter is set, only objects whose names do not contain the delimiter character (after an optionally specified prefix) are deleted. Scanned objects whose names contain the delimiter have part of their name up to the last occurrence of the delimiter (after the optional prefix) returned as a set of prefixes. Note: Only ‘/’ is a supported delimiter character at this time.

--dry-run

Displays a list of objects which would be deleted by this command, if it were run without –dry-run. If –dry-run is passed, no objects will actually be deleted.

--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

--force

Do not ask for confirmation prior to performing the bulk delete.

--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/Content/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

-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’

--object-name [text]

Delete all versions of the given objectName. Only one of prefix or objectName can be given as input. Omit this parameter to delete all objects in the bucket.

--parallel-operations-count [integer]

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]

--prefix [text]

Delete all object versions with the given prefix. Only one of prefix or objectName can be given as input. Omit this parameter to delete all objects in the bucket.

Examples

Deleting all object versions in the bucket

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket

Delete all object versions that match a given prefix

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --prefix level1/level2/ --prefix myprefix

You can delete all object versions that match a given prefix by specifying the –prefix flag. In the above example, “–prefix myprefix” would match object names such as myprefix_textfile1.txt, myprefix_myImage.png etc.

If you have named your objects so that they exist in Object Storage as a hierarchy, e.g. level1/level2/level3/myobject.txt, then you can delete objects at a given level (and all sub levels) by specifying a prefix:

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --prefix level1/level2/

This will delete all object versions of the form level1/level2/<object name>, level1/level2/leve3/<object name>, level1/level2/leve3/level4/<object name> etc.

Limiting deleted objects using a prefix and delimiter

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --prefix level1/level2/ --delimiter /

If you have named your objects so that they exist in Object Storage as a hierarchy, e.g. level1/level2/level3/myobject.txt, and you only want to delete objects at a given level of the hierarchy, e.g. example everything of the form level1/level2/<object name> but not level1/level2/leve3/<object name> or any other sub-levels, you can specify a prefix and delimiter. Currently the only supported delimiter is /

Deleting all object versions using object name

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --object-name <object name>

You can delete all object versions that match a given object name by specifying the –object-name flag. Both -object-name and -prefix cannot be given in the same command

Previewing what would be deleted

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --dry-run

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --prefix level1/level2/ --dry-run

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --prefix level1/level2/ --delimiter / --dry-run

For any bulk-delete-versions command you can get a list of all object versions which would be deleted, but without actually deleting them, by using the –dry-run flag

Do not prompt for delete

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --force

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --prefix level1/level2/ --force

 oci os object bulk-delete-versions -ns mynamespace -bn mybucket --prefix level1/level2/ --delimiter / --force

By default, the bulk-delete-versions command will prompt you prior to deleting objects. To suppress this prompt, pass the –force option.

Example using required parameter

Copy the following CLI commands into a file named example.sh. Run the command by typing “bash example.sh” and replacing the example parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-like shell. You need to set up the OCI configuration and appropriate security policies before trying the examples.
