Parameter	Type	Description
script	string	Filename of script to check. This is case-sensitive.
host	string	_(Optional)_ Hostname/IP of the target server. Optional. Defaults to current server if not provided.

**Returns:** boolean True if the specified script is running, and false otherwise. ## Remarks RAM cost: 1 GB Returns a boolean indicating whether any instance of the specified script is running on the target server, regardless of its arguments. This is different than the [isRunning](./bitburner.ns.isrunning.md) function because it does not try to identify a specific instance of a running script by its arguments. ## Example ```js //The function call will return true if there is any script named foo.js running on the foodnstuff server, and false otherwise: ns.scriptRunning("foo.js", "foodnstuff"); //The function call will return true if there is any script named “foo.js” running on the current server, and false otherwise: ns.scriptRunning("foo.js", ns.getHostname()); ```
