<a name="efs_example_efs_CreateFileSystem_section"></a>

The following code examples show how to use `CreateFileSystem`.

------
#### [ CLI ]

**AWS CLI**  
**To create an encrypted file system**  
The following `create-file-system` example creates an encrypted file system using the default CMK. It also adds the tag `Name=my-file-system`.  

```
aws efs create-file-system \
    --performance-mode generalPurpose \
    --throughput-mode bursting \
    --encrypted \
    --tags Key=Name,Value=my-file-system
```
Output:  

```

    "LifeCycleState": "creating",
    "Name": "my-file-system",
    "NumberOfMountTargets": 0,
    "SizeInBytes": {
        "Value": 0,

        "ValueInStandard": 0
    },
    "PerformanceMode": "generalPurpose",

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: Creates a new, empty file system. The token used to ensure idempotent creation will be generated automatically and can be accessed from the `CreationToken` member of the returned object.**  

```
New-EFSFileSystem
```
**Output:**  

```
CreationTime         : 5/26/2015 4:02:38 PM
CreationToken        : 1a2bff54-85e0-4747-bd95-7bc172c4f555
FileSystemId         : fs-1a2b3c4d
LifeCycleState       : creating
Name                 :
NumberOfMountTargets : 0
OwnerId              : 123456789012
SizeInBytes          : Amazon.ElasticFileSystem.Model.FileSystemSize
```
**Example 2: Creates a new, empty file system using a custom token to ensure idempotent creation.**  

```
New-EFSFileSystem -CreationToken "MyUniqueToken"
```
+  For API details, see [CreateFileSystem](https://docs.aws.amazon.com/powershell/v4/reference) in *AWS Tools for PowerShell Cmdlet Reference (V4)*. 

**Tools for PowerShell V5**  
**Example 1: Creates a new, empty file system. The token used to ensure idempotent creation will be generated automatically and can be accessed from the `CreationToken` member of the returned object.**  

```
New-EFSFileSystem
```
