# Listing LF-Tag expressions
<a name="TBAC-listing-expressions"></a>

 You can list the LF-Tag expressions that you have the Describe permissions on. Data lake administrators, LF-Tag expression creators, and Read-only administrators implicitly can see all tag expressions in their account. 

You can list LF-Tag expressions by using the Amazon Lake Formation console, the API, or the Amazon Command Line Interface (Amazon CLI).

------
#### [ Console ]

**To list LF-Tag expressions (console)**

1. Open the Lake Formation console at [https://console.amazonaws.cn/lakeformation/](https://console.amazonaws.cn/lakeformation/).

   Sign in as the LF-Tag expression creator, as a data lake administrator, or as a principal that has been granted permissions on LF-Tag expressions and that has the `lakeformation:ListLFTagExpressions` IAM permission.

1. In the navigation pane, under ** Permissions**, **LF-Tags and permissions**.

1. Choose **LF-Tag expressions** tab to see the expressions. This section shows the information about the existing LF-Tag expressions, including the expression name, the expression itself with links to the included tags, and options to create, edit, or delete expressions.

#### [ Amazon CLI ]

**To list LF-Tags (Amazon CLI)**
+ To list LF-Tag expressions using the Amazon CLI, you can use the list-lf-tag-expressions command. The request syntax is: 

  ```
  aws lakeformation list-lf-tag-expressions \
  -- catalog-id "123456789012" \
  -- max-items "100" \
  -- next-token "next-token"
  ```

   Where:
  + `catalog-id` is the Amazon account ID of the Data Catalog you want to list tag expressions for .
  + `max-items` specifies the maximum number of tag expressions to return. If this parameter is not used, the default value is 100.
  + `next-token` is a continuation token if the results were truncated in a previous request.

  The response will include a list of LF-Tag expressions and a next token if applicable.
