# Use `UpdateDocument` with a CLI
<a name="ssm_example_ssm_UpdateDocument_section"></a>

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

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

**AWS CLI**  
**To create a new version of a document**  
The following `update-document` example creates a new version of a document when run on a Windows computer. The document specified by `--document` must be in JSON format. Note that `file://` must be referenced followed by the path of the content file. Because of the `$` at the beginning of the `--document-version` parameter, On Windows you must surround the value with double quotes. On Linux, MacOS, or at a PowerShell prompt, you must surround the value with single quotes.  
**Windows version**:  

```
aws ssm update-document \
    --name "RunShellScript" \
    --content "file://RunShellScript.json" \
    --document-version "$LATEST"
```
**Linux/Mac version**:  

```
aws ssm update-document \
    --name "RunShellScript" \
    --content "file://RunShellScript.json" \
    --document-version '$LATEST'
```
Output:  

```
