title: awk OFS not producing expected value
body: <p>I have a file</p>
  
  <pre><code>[root@nmk~]# cat file
  abc&gt;
  sssd&gt;
  were&gt;
  </code></pre>
  
  <p>I run both these variations of the awk commands</p>
  
  <pre><code>[root@nmk~]# cat file | awk -F\&gt;  ' { print $1}' OFS=','
  abc
  sssd
  were
  
  [root@nmk~]# cat file | awk -F\&gt;  ' BEGIN { OFS=","}  { print $1}' 
  abc
  sssd
  were
  [root@nmk~]# 
  </code></pre>
  
  <p>But my expected output is</p>
  
  <pre><code>abc,sssd,were
  </code></pre>
  
  <p>What's missing in my commands ?</p>
