Would something like this be useful?

Code:

String command="ps -A -U "+System.getProperty("user.name")+" -d";
try {
      String line;
      Process p = Runtime.getRuntime().exec(command);
      BufferedReader input =new BufferedReader(new InputStreamReader(p.getInputStream()));
      while ((line = input.readLine()) != null) {
        System.out.println(line);
      }
      input.close();
    }catch (Exception err) {
      err.printStackTrace();
    }

Of course you would need to modify it to reflect for searching for smbd.

Hi -

1. Runtime.exec ("/etc/init.d/snmpd status") to get the service current status (for example)
2. Use Process streams to read the result.

For example (pseudo code: untested):

Code:

Process process = Runtime.getRuntime ().exec ("/etc/init.d/snmpd status");
InputStream stdout = process.getInputStream ();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(stdin));
...
String input = scan.nextLine();
...

That too

To add to that, to check for the example the OP posted, it would be "/etc/init.d/smb status"

corp769 -

You and I happened to post the same answer at the same time (your post didn't show until after I clicked "send").

I guess that proves great minds run in the same channel

.

Anyway, I'm hoping the OP is squared away.

Yes they do

I haven't programmed with java in such a long time, yet I knew what to look for.... I think it's been 6 or 7 years since I touched java. I've been messing with perl and python lately...
