I'm using filebeat to read some log files and I need to start filebeat using a java program. And the filebeat commands are executed using the windows powerShell. I used the following code but it didn't work.

try {  
ProcessBuilder b1 = new ProcessBuilder("powershell.exe", "/c", "cd "C:\Program Files\Filebeat" && ./filebeat -e -c filebeat.yml -d "publish"\");  
b1.redirectErrorStream(true);  
Process p1 = b1.start();  
BufferedReader r1 = new BufferedReader(new InputStreamReader(p1.getInputStream()));  
String line1;  
while (true) {  
line1 = r1.readLine();  
if (line1 == null) { break; }  
System.out.println(line1);  
}

```
}catch(Exception e) {

}
```

Try this

```java
ProcessBuilder pb = new ProcessBuilder("C:\\Program Files\\Filebeat\\filebeat.exe", "-c", "C:\\Program Files\\Filebeat\\filebeat.yml", "-e");
pb.redirectErrorStream(true);
Process p = pb.start();

BufferedReader bri = new BufferedReader(new InputStreamReader(p.getInputStream()));

String line;
while ((line = bri.readLine()) != null) {
   System.out.println(line);
}
p.waitFor();

```
