Returns a boolean indicating whether the specified script is running on the target server. If you use a PID instead of a filename, the hostname and args parameters are unnecessary. Remember that a script is semi-uniquely identified by both its name and its arguments. (You can run multiple copies of scripts with the same arguments, but for the purposes of functions like this that check based on filename, the filename plus arguments forms the key.)

## Example
|
|
|
|
|
|
```js
|
|
//The function call will return true if there is a script named foo.js with no arguments running on the foodnstuff server, and false otherwise:
|
|
ns.isRunning("foo.js", "foodnstuff");
|
|
|
|
//The function call will return true if there is a script named foo.js with no arguments running on the current server, and false otherwise:
|
|
ns.isRunning("foo.js", ns.getHostname());
|
|
|
|
//The function call will return true if there is a script named foo.js running with the arguments 1, 5, and “test” (in that order) on the joesguns server, and false otherwise:
|
|
ns.isRunning("foo.js", "joesguns", 1, 5, "test");
|
|
```
