rm - Object Storage Service - Alibaba Cloud Documentation Center

This topic describes how to run the rm command to delete objects, parts, or buckets that you no longer need to avoid unnecessary charges.

Usage notes

This topic provides sample command lines that are based on the 64-bit Linux system. For other systems, replace ./ossutil64 in the commands with the specific binary name. For more information, see ossutil.

Syntax

./ossutil64 rm oss://bucketname[/prefix]
[-r, --recursive]
[-b, --bucket]
[-m, --multipart]
[-a, --all-type]
[-f, --force]
[--include <value>]
[--exclude <value>]
[--version-id <value>] 
[--all-versions]
[--payer <value>]
[--encoding-type <value>]

The following table describes the parameters that you can configure to run the rm command.

Parameter	Description
bucketname	The name of the bucket in which the objects you want to delete are stored.
prefix	The resources in the bucket whose names contain the specified prefix, such as directories or objects.
-r, --recursive	If you specify this parameter, ossutil deletes all objects whose names contain the specified prefix from the bucket. If you do not specify this parameter, ossutil deletes only specified objects.
-b, --bucket	Specifies that the command is run to delete a bucket. This option can be configured only when you run the command to delete a bucket.
-m, --multipart	Specifies that the operation is performed on the incomplete multipart upload tasks in a bucket.
-a, --all-type	Specifies that the operation is performed on the objects and incomplete multipart upload tasks in the bucket.
-f, --force	Specifies the operation to forcefully perform. The operation is performed without a prompt for confirmation.
--include	Specifies that the command applies to all objects that meet specified conditions.
--exclude	Specifies that the command applies to all objects that do not meet specified conditions.
--version-id	The version ID of the object that you want to delete. This parameter applies only when the versioning status of the bucket is enabled or suspended.
--all-versions	Specifies all versions of objects. This option applies only to objects in buckets for which versioning is enabled or suspended. You can specify only one of the --version-id and --all-versions options in a single rm command.
--payer	Specifies the payer of the request. If you want the requester who accesses the resources in the specified path to pay the traffic and request fees, set this parameter to requester.
--encoding-type	The method used to encode the prefix specified by the object name that follows `oss://bucket_name` in the full object path. Valid value: url. If you do not specify this option, the prefix is not encoded.

Delete objects

Warning

Objects cannot be restored after they are deleted. Exercise caution when you perform this operation.

If you use the rm command with or without the -r option to delete one or more objects, the ListObjects (GetBucket) and DeleteObject operations are called. In this case, you are charged for sending PUT requests. For more information, see API operation calling fees.

Examples
- Delete a single object
  Delete an object named exampleobject.txt from a bucket named examplebucket.
```
./ossutil64 rm oss://examplebucket/exampleobject.txt
```
- Delete all objects whose names contain the "test" prefix from a bucket named examplebucket.
```
./ossutil64 rm oss://examplebucket/test -r
```
- Delete all objects whose names contain the ".png" suffix from a bucket named examplebucket.
```
./ossutil64 rm oss://examplebucket  --include "*.png" -r
```
- Delete objects whose names contain the string "abc" and do not contain the ".jpg" or ".txt" suffix from a bucket named examplebucket.
```
./ossutil64 rm oss://examplebucket  --include "*abc*" --exclude "*.jpg" --exclude "*.txt" -r
```
- Delete the specified version of an object named exampleobject.txt from a versioned bucket named examplebucket.
```
./ossutil64 rm oss://examplebucket/exampleobject.txt --version-id  CAEQARiBgID8rumR2hYiIGUyOTAyZGY2MzU5MjQ5ZjlhYzQzZjNlYTAyZDE3****
```
  For more information about how to query all versions of an object, see Is.
- Delete all versions of an object named exampleobject.txt from a versioned bucket named examplebucket.
```
./ossutil64 rm oss://examplebucket/exampleobject.txt --all-versions
```
- Delete all versions of all objects from a versioned bucket named examplebucket.
```
./ossutil64 rm oss://examplebucket --all-versions -r
```
Response
After the specified objects are deleted by running the preceding commands, a similar output is displayed, which indicates the number of deleted objects and the time used to delete the objects:
```
Succeed: Total 8 objects. Removed 8 objects.
0.106852(s) elapsed
```

Delete parts

If you use the rm command with multiple options to delete parts, the ListMultipartUploads, ListParts, and AbortMultipartUpload operations are called. In this case, you are charged for sending GET requests when the ListMultipartUploads and ListParts operations are called and for sending PUT requests when the AbortMultipartUpload operation is called. For more information, see API operation calling fees.

Examples
- Specify the -m option in the command to delete parts that are generated by incomplete multipart upload tasks of an object named exampleobject.txt from a bucket named examplebucket.
```
./ossutil64 rm -m oss://examplebucket/exampleobject.txt
```
- Specify the -m and -r options in the command to recursively delete parts that are generated by the incomplete multipart upload tasks of objects whose names contain the "test" prefix from a bucket named examplebucket.
```
./ossutil64 rm -m oss://examplebucket/test -r 
Do you really mean to remove recursively multipart uploadIds of oss://examplebucket/test(y or N)? y 
```
- Specify the -a and -r options in the command to recursively delete objects whose names contain the "src" prefix and parts that are generated by the incomplete multipart upload tasks of these objects from a bucket name examplebucket.
```
./ossutil64 rm  oss://examplebucket/src -a -r
Do you really mean to remove recursively objects and multipart uploadIds of oss://examplebucket/src(y or N)? y
```
Response
After the specified objects and parts are deleted by running the preceding commands, a similar output is displayed, which indicates the number of deleted objects, the number of multipart upload tasks by which the deleted parts are generated, and the time used to delete the objects and parts:
```
Succeed: Total 1 objects, 3 uploadIds. Removed 1 objects, 3 uploadIds.
1.922915(s) elapsed
```

Delete buckets

Delete the examplebucket bucket that contains no objects or parts.
```
./ossutil64 rm oss://examplebucket -b
Do you really mean to remove the Bucket: examplebucket(y or N)? y
```
A similar output is displayed, which indicates the name of the deleted bucket and the time used to delete the bucket:
```
Removed Bucket: examplebucket
2.230745(s) elapsed
```
Delete a bucket named examplebucket and all objects and parts in the bucket.
Warning
If you run the following command, all data in the bucket is deleted and deleted data cannot be recovered. Proceed with caution.
```
./ossutil64 rm  oss://examplebucket -b -a -r
Do you really mean to remove recursively objects and multipart uploadIds of oss://examplebucket(y or N)? y
Do you really mean to remove the Bucket: examplebucket(y or N)? y
```
A similar output is displayed, which indicates the number of deleted objects, the number of multipart upload tasks by which the deleted parts are generated, the name of the deleted bucket, and the time used to delete the objects, parts, and bucket:
```
Succeed: Total 189 objects, 37 uploadIds. Removed 189 objects, 37 uploadIds.
Removed Bucket: examplebucket
9.184193(s) elapsed
```

Common options

If you use ossutil to switch to a bucket that is located in another region, add the -e option to the command to specify the endpoint of the region in which the specified bucket is located. If you use ossutil to switch to a bucket that belongs to another Alibaba Cloud account, you can add the -i option to the command to specify the AccessKey ID of the specified account, and add the -k option to the command to specify the AccessKey secret of the specified account.

For example, you can run the following command to delete an object named exampletest.png from a bucket named testbucket, which is located in the China (Shanghai) region and belongs to another Alibaba Cloud account:

./ossutil64 rm oss://testbucket/exampletest.png -e oss-cn-shanghai.aliyuncs.com -i LTAI4Fw2NbDUCV8zYUzA****  -k 67DLVBkH7EamOjy2W5RVAHUY9H****
