    Default unable to run tshark command in java on ubuntu

    Hello,

    I am trying to run tshark command using runtime environment in java on ubuntu . My code is as follows :-


    try {
    String destip = map1.get((String) innObj.get("value"));
    Runtime run = Runtime.getRuntime();
    String tshk = "/usr/bin/tshark -r /home/pratibha/Desktop/vox.pcap -Y \"ip.dst == "
    + destip
    + " && http\" -T fields -e tcp.port -e col.Info";
    Process pr = run.exec(tshk);

    int exitcode = pr.waitFor();
    System.out.println(exitcode);
    BufferedReader buf = new BufferedReader(
    new InputStreamReader(pr.getInputStream()));

    String line = "";
    while ((line = buf.readLine()) != null) {
    System.out.println(line);
    }

    } catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    }


    map1 is hashmap which contains the destination ip adress
    When i run the above code the exit code for process (pr) is 1 and hence the tshark command is not executing properly.
    Please help

    Separate the command line arguments. Suggested Reading:
    ProcessBuilder (Java Platform SE 7 )
    And I would not recommend running consecutive commands that depend upon a previous in a single exec operation - these operate at the shell level. If you must, I would recommend writing a script file containing the commands and then executing that script using ProcessBuilder or Runtime.exec
