mkdir - Object Storage Service - Alibaba Cloud Documentation Center

To organize objects in a bucket, you can use directories. This topic describes how to run the mkdir command to create directories in ossutil.

Important 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 mkdir oss://bucketname/dirname [--encoding-type <value>]

The following table describes the parameters that you can configure when you run this command to create directories.


Parameter	Description
bucketname	The name of the bucket in which you want to create directories.
dirname	The name of the directory that you want to create. A directory name must end with a forward slash (/). If you do not end the directory name with a forward slash (/), ossutil automatically adds one at the end of the name.
--encoding-type	The encoding type used to encode the directory name, which is specified by the part that follows `oss://bucket_name` in the value of dirname. Valid value: url. If you do not specify this parameter, the directory name is not encoded.

Examples

You can perform the following steps to upload an object to a specified directory:

Create a directory.
- Create a single-level directory
```
./ossutil64 mkdir oss://examplebucket/dir/
```
  If a similar output is returned, a directory named dir/ is created in the bucket named examplebucket:
```
0.385877(s) elapsed
```
- Create a multi-level directory
  To further classify objects stored in a directory, you can create multi-level directories. For example, you can run the following command to create a multi-level directory oss://examplebucket/Photo/2021/ to store the snapshots that are generated in 2021:
```
./ossutil64 mkdir oss://examplebucket/Photo/2021/ 
```
  If you accidentally delete the 2021/ directory and no other objects are stored in the Photo/ directory, the Photo/ directory is also deleted.
Upload an object to a directory
You can run the following command to upload an object named exampleobject.txt to the dir/ directory in a bucket named examplebucket:
```
./ossutil64 cp exampleobject.txt oss://examplebucket/dir/
```
If a similar output is returned, the object is uploaded to the specified directory:
```
Succeed: Total num: 1, size: 0. OK num: 1(upload 1 files).

average speed 0(byte/s)
```

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 create a directory named dir/ in a bucket named examplebucket, which is located in the China (Hangzhou) region and owned by another Alibaba Cloud account:

./ossutil64 mkdir oss://examplebucket/dir/ -e oss-cn-hangzhou.aliyuncs.com -i LTAI4Fw2NbDUCV8zYUzA****  -k 67DLVBkH7EamOjy2W5RVAHUY9H****
