Thread: 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

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

Hey Thanks , I am getting the result now after writing a shell script .. Thank You very much !!
