title: How to read a text file in real time with Java ON LINUX?
body: <p>I put 'ON LINUX' in caps not to annoy you but because I have already been able to do this on Windows using 3 different file reading Classes.
  FileIntputStream
  BufferedReader
  RandomAccessFile 
  (The last two I am sure of but the first could be wrong - my memory is baaad.) All of these are working perfectly on windows for me.
  My intended use of these readers is to read a text file line by line in real time, meaning, when a new version of this file is saved with a new line appended to it, the java program reads this line, does something with it and then continues checking for another new line.</p>
  
  <p>I tried compiling using Java 7 openJDK, Java 7 Oracle, and Java 8 Oracle environments and all the resulting .jars worked fine on windows, and since Java is cross-platform I assumed they would work on Linux too (right?), yet every version I compile has failed when tested on linux.
  This was brought to my attention by a community forum member running linux Red Hat, no errors/exceptions, looked like it was running but just didn't work. I installed Ubuntu today and tried it for myself: The readers will read the original file fine but do not "stream" the file in real time. Changes to the file go unnoticed.
  I am very confused as to how this is possible and honestly I'm surprised it hasn't been brought up anywhere (as far as I can tell lol). Hopefully this means that I've made a stupid mistake somewhere in regards to ensuring linux compatibility that someone might track down.
  Any and all help/answers/workarounds are appreciated!</p>
  
  <p>Here is an example of the code I am trying to implement into my program:</p>
  
  <pre><code>import java.io.File;
  import java.io.FileNotFoundException;
  import java.io.IOException;
  import java.io.RandomAccessFile;
  
  public class Driver {
  
      public static void main(String[] args) {
          RandomAccessFile reader = null;
          try {
              reader = new RandomAccessFile(new File("/home/citats/csgo/console.log"), "r");
          } catch (FileNotFoundException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          }
          String currLine;
          Boolean done = false;
          while (!done) {
              try {
                  if ((currLine = reader.readLine()) != null)
                  {
                      System.out.println(currLine);
                      if (currLine.equals("done"))
                          done = true;
                  } else
                      try {
                          Thread.sleep(1000);
                      } catch (InterruptedException e) {
                          // TODO Auto-generated catch block
                          e.printStackTrace();
                      }
              } catch (IOException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
              }
          }
          reader.close();
      }
  }
