NETSH produces no output

Question

I am trying to use following command.

Runtime.getRuntime().exec("netsh -c interface dump > c:\\location1.txt");

But it produces no output.

I know we have to separate command and its arguments i tried but still failed.

I used following way.

Runtime.getRuntime().exec("netsh",new String[] "-c", "interface", "dump >", "c:\\location1.txt");

But still produces no output.

If anyone knows how to use all or some of the NETSH commands using runtime then it will be great helpful.

You can try using ProcessBuilder

ProcessBuilder pb=new ProcessBuilder(command);
pb.redirectErrorStream(true);
Process process=pb.start();
BufferedReader inStreamReader = new BufferedReader(
    new InputStreamReader(process.getInputStream())); 

while(inStreamReader.readLine() != null){
    //do something with commandline output.
}

it throws exception here it is "Exception in thread "main" java.io.IOException: Cannot run program "netsh -c interface dump > C:\local.txt": CreateProcess error=2, The system cannot find the file specified at java.lang.ProcessBuilder.start(Unknown Source) at com.kamani.proxyloader.ExecuteCommand.main(ExecuteCommand.java:16) Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified" – Nirav Kamani Jan 09 '14 at 12:01

Should be like this `new ProcessBuilder("netsh.exe", "-c", "interface","dump");` No `> C:\local.txt` at all. – PeterMmm Jan 09 '14 at 12:08

it's still not working.All other command works but i don't know why above command is not working. – Nirav Kamani Jan 09 '14 at 08:13
You cannot redirect the output. The redirect `>` is part of a shell command. You may catch the `netsh`output as @A Paul said or start `cmd.exe` with a commandline. Look here: http://stackoverflow.com/questions/5928225/how-to-make-pipes-work-with-runtime-exec – PeterMmm Jan 09 '14 at 08:55
ya you are right but i am still unable to understand can you tell me how can i resolve this issue? – Nirav Kamani Jan 09 '14 at 12:02
