## 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 | Hostname 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](./bitburner.ns.isrunning.md) 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());
