# Exercise 5: Create an Alias (AWS CLI)
<a name="gs-cli-create-alias"></a>

An alias is a pointer to a specific version of a bot. With an alias you can easily update the version that your client applications are using. For more information, see [Versioning and Aliases](versioning-aliases.md).To run the commands in this exercise, you need to know the region where the commands will be run. For a list of regions, see [Model Building Quotas](gl-limits.md#gl-limits-model-building).

**To create an alias (AWS CLI)**

1. In the AWS CLI, get the version of the `OrderFlowersBot` bot that you created in [Exercise 4: Publish a Version (AWS CLI)](gs-cli-publish.md). 

   ```
   aws lex-models get-bot \
       --region region \
       --name OrderFlowersBot \
       --version-or-alias version > OrderFlowersBot_V5.json
   ```

1. In a text editor, open **OrderFlowersBot\$1v5.json**. Find and record the version number.

1. In the AWS CLI, create the bot alias:

   ```
   aws lex-models put-bot-alias  \
       --region region \
       --name PROD \
       --bot-name OrderFlowersBot \
       --bot-version version
   ```

   The following is the reponse from the server:

   ```
   {
       "name": "PROD",
       "createdDate": timestamp,
       "checksum": "checksum",
       "lastUpdatedDate": timestamp,
       "botName": "OrderFlowersBot",
       "botVersion": "1"
   }}
   ```
