The read-symlink command is used to query the information about a symbolic link, including the ETag and last update time. To run this command to query the information about a symbolic link, you must have read permissions on the symbolic link.

Notice Sample command lines in this topic are based on the 64-bit Linux system. For other systems, replace ./ossutil64 in the commands with the corresponding binary name. For more information, see ossutil.

Command syntax

./ossutil64 read-symlink oss://bucketname/objectname [--encoding-type <value>] [--payer <value>]

The following table describes the parameters that you can configure in this command.

Parameter Description
bucketname The name of the bucket in which the symbolic link you want to query is stored.
objectname The name of the symbolic link you want to query.
--encoding-type The method used to encode the name of the symbolic link. Valid value: url. If you do not specify this parameter, the name of the symbolic link is not encoded.

Examples

Query the information about a symbolic link named test.jpg in a bucket named examplebucket. 

./ossutil64 read-symlink oss://examplebucket/test.jpg

The following output result indicates that the information about test.jpg is obtained, including the ETag value, last update time, and the object to which the symbolic link points. According to the result, test.jpg points to an object named example.jpg. 

Etag                    : 938F26218CE422CBEEE0B6543A2B2D

If the object that you query is not a symbolic link, NotSymlink is returned.

Common options

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

For example, you can run the following command to query the information about a symbolic link named testobject.png in a bucket named testbucket, which is located in the China (Shanghai) region and owned by another Alibaba Cloud account: 

./ossutil64 read-symlink oss://testbucket/testobject.png -e oss-cn-shanghai.aliyuncs.com -i LTAI4Fw2NbDUCV8zYUzA****  -k 67DLVBkH7EamOjy2W5RVAHUY9H****
