## NS.scriptRunning() method
Check if any script with a filename is running.
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 of target server. |
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 function because it does not try to identify a specific instance of a running script by its arguments.
## Example 1
```ts
// NS1:
//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");
//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());
```
\*
## Example 2
```ts
// NS2:
//The function call will return true if there is any script named foo.script running on the foodnstuff server, and false otherwise:
ns.scriptRunning("foo.script", "foodnstuff");
//The function call will return true if there is any script named “foo.script” running on the current server, and false otherwise:
ns.scriptRunning("foo.script", ns.getHostname());
