title: Double new line as delimiter in awk and tail function
body: <p>I need to separate a text file which looks like this</p>
  
  <pre><code>1
  00:01:03:321 --&gt; 00:01:04:321
   Randomtext1
  
  2
  00:02:03:321 --&gt; 00:03:04:321
   Randomtext2
  Still random text2
  3rd line of randomtext2
  
  3
  00:04:03:321 --&gt; 00:05:04:321
   Randomtext3
  Stillrand
  </code></pre>
  
  <p>To blocks including ordinal number line, timers line, content lines and then 
  delete ordinal numbers line.
  By separating code to blocks looking like this I mean that I want to make all those lines as 1 record (so it could be easier to delete first two(pure new line and ordinal number line))
  This is code:</p>
  
  <pre><code>#!/bin/bash
  name=text.sub
  name2=text2.sub
  awk '
  BEGIN {FS="\n\n";
  
  }
  { 
  tail -n+1 $1;
  
  }' $name &gt; $name2
  </code></pre>
  
  <p>expected output will be</p>
  
  <pre><code>00:01:03:321 --&gt; 00:01:04:321
   Randomtext1
  00:02:03:321 --&gt; 00:03:04:321
   Randomtext2
  Still random text2
  3rd line of randomtext2
  00:04:03:321 --&gt; 00:05:04:321
   Randomtext3
  Stillrand
  </code></pre>
