About a week ago, I decided to format the whole harddisk and start anew.
Of course, this meant losing the triple-boot configuration and Wubi along with it. I was fine with losing the windows, but didn’t want to lose the Wubi Ubuntu installation.

How to get the output of a console application from Java

Of course; I was trying to get a thread dump using jstack here. You would need to change the command that Runtime.exec() executes to your liking.
Process threadDump=Runtime.getRuntime().exec("jstack -l "+pid);
BufferedReader br=new BufferedReader(new InputStreamReader(threadDump.getInputStream()));
while(true)
{
String line=br.readLine();
if(line==null)
break;
else {
//Do whatever you want
}
How to get the process id after running an application from Java under Linux

Use the following sample code to get the pid(process id) on *nix variants, after running it as a command from Java using Runtime.exec() .
The command variable, in my case, was running another Java application.
try {
Process process=Runtime.getRuntime().exec(new String [] {"sh","-c",command+" & echo $!"} );
BufferedReader br=new BufferedReader(new InputStreamReader(process.getInputStream()));String ps=br.readLine();
int pid=Integer.valueOf(ps);
} catch (IOException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
