title: Can i use awk in java?
body: <p>I tried the code below but it doesn't work. Nevertheless, if I try to cat the file, it works and prints the whole content of the file. </p>
  
  <p>But the reason I tried using awk is that I don't need the whole content, I only need some parts of each line.</p>
  
  <pre><code>Runtime r = Runtime.getRuntime();
  Process p = r.exec("awk -F\":\" '/in/ {print $3}' file.awk"); 
  p.waitFor();
  BufferedReader in=new BufferedReader(new InputStreamReader(p.getInputStream()));
  System.out.println("esto es una \"prueba\"");
  String valor = "";
  while ((valor = in.readLine())!= null){
      System.out.println(valor);
  }
  </code></pre>
