# NSExistsCommand

A command that determines whether a scriptable object exists.

## Declaration

```swift
class NSExistsCommand
```

## Overview

Overview An instance of NSExistsCommand determines whether a specified scriptable object, such as a word, paragraph, or image, exists. When an instance of NSExistsCommand is executed, it evaluates the receiver specifier for the command to determine if it specifies any objects. NSExistsCommand is part of Cocoa’s built-in scripting support. Most applications don’t need to subclass NSExistsCommand.
