This is different than the isRunning function because it does not try to identify a specific instance of a running script by its arguments. Signature: ```typescript scriptRunning(script: string, host: string): boolean; ``` ## Parameters | Parameter | Type | Description | | --- | --- | --- | | script | string | Filename of script to check. This is case-sensitive. | | host | string | Host or IP of target server. | Returns: boolean True if the specified script is running, and false otherwise. ## Remarks RAM cost: 1 GB ## Example 1 ```ts //The function call will return true if there is any script named foo.script running on the foodnstuff server, and false otherwise: scriptRunning("foo.script", "foodnstuff"); ``` ## Example 2 ```ts //The function call will return true if there is any script named “foo.script” running on the current server, and false otherwise: scriptRunning("foo.script", getHostname()); ```
