# Tag an existing session

The  `tag` command in MarinaBox CLI is used to add or update a tag for a session. Tags help with session identification and categorization and can be applied to both running and closed sessions.

***

## Command Syntax

```bash theme={null}
mb local tag <SESSION_ID> <TAG>
```

***

## Description

This command allows you to:

* Assign a new tag to a session for better organization.
* Update the tag of an existing session (running or closed).

Tags are especially useful for grouping sessions based on use cases or workflows.

***

## Example Usage

### Add a Tag to a Running Session:

```bash theme={null}
mb local tag abc123xyz Development
```

### Update the Tag for a Closed Session:

```bash theme={null}
mb local tag xyz789abc ArchivedSession
```

***

## Example Output

For a successful tagging operation:

```bash theme={null}
Tag updated successfully
```

If the `session_id` is invalid or the session does not exist:

```bash theme={null}
Session not found
```

***

## Notes

* Use the `session_id` from the `list` or `list-closed` command to ensure you're tagging the correct session.
* Tags are optional but can significantly improve session tracking and organization.
* This command works for both active and closed sessions.
