# Use `CreateInvalidation` with a CLI
<a name="cloudfront_example_cloudfront_CreateInvalidation_section"></a>

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

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

**AWS CLI**  
**To create an invalidation for a CloudFront distribution**  
The following `create-invalidation` example creates an invalidation for the specified files in the specified CloudFront distribution:  

```
aws cloudfront create-invalidation \
    --distribution-id EDFDVBD6EXAMPLE \
    --paths "/example-path/example-file.jpg" "/example-path/example-file2.png"
```
Output:  

```
{
    "Location": "https://cloudfront.amazonaws.com/2019-03-26/distribution/EDFDVBD6EXAMPLE/invalidation/I1JLWSDAP8FU89",
    "Invalidation": {
        "Id": "I1JLWSDAP8FU89",
        "Status": "InProgress",
        "CreateTime": "2019-12-05T18:24:51.407Z",
        "InvalidationBatch": {
            "Paths": {
                "Quantity": 2,
                "Items": [
                    "/example-path/example-file2.png",
                    "/example-path/example-file.jpg"
                ]
            },
            "CallerReference": "cli-1575570291-670203"
        }
    }
}
```
In the previous example, the AWS CLI automatically generated a random `CallerReference`. To specify your own `CallerReference`, or to avoid passing the invalidation parameters as command line arguments, you can use a JSON file. The following example creates an invalidation for two files, by providing the invalidation parameters in a JSON file named `inv-batch.json`:  

```
aws cloudfront create-invalidation \
    --distribution-id EDFDVBD6EXAMPLE \
    --invalidation-batch file://inv-batch.json
```
Contents of `inv-batch.json`:  

```
{
    "Paths": {
        "Quantity": 2,
        "Items": [
            "/example-path/example-file.jpg",
            "/example-path/example-file2.png"
        ]
    },
    "CallerReference": "cli-example"
}
```
Output:  

```
{
    "Location": "https://cloudfront.amazonaws.com/2019-03-26/distribution/EDFDVBD6EXAMPLE/invalidation/I2J0I21PCUYOIK",
    "Invalidation": {
        "Id": "I2J0I21PCUYOIK",
        "Status": "InProgress",
        "CreateTime": "2019-12-05T18:40:49.413Z",
        "InvalidationBatch": {
            "Paths": {
                "Quantity": 2,
                "Items": [
                    "/example-path/example-file.jpg",
                    "/example-path/example-file2.png"
                ]
            },
            "CallerReference": "cli-example"
        }
    }
}
```

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This example creates a new invalidation on a distribution with an ID of EXAMPLENSTXAXE. The CallerReference is a unique ID chosen by the user; in this case, a time stamp representing May 15, 2019 at 9:00 a.m. is used. The \$1Paths variable stores three paths to image and media files that the user does not want as part of the distribution's cache. The -Paths\$1Quantity parameter value is the total number of paths specified in the -Paths\$1Item parameter.**  

```
$Paths = "/images/*.gif", "/images/image1.jpg", "/videos/*.mp4"
New-CFInvalidation -DistributionId "EXAMPLENSTXAXE" -InvalidationBatch_CallerReference 20190515090000 -Paths_Item $Paths -Paths_Quantity 3
```
**Output:**  

```
Invalidation                         Location
