title: AWK remove blank lines
body: <p>The <code>/./</code> is removing blank lines for the first condition <code>{ print "a"$0 }</code> only, how would I ensure the script removes blank lines for every condition ?</p>
  
  <pre><code>awk -F, '/./ { print "a"$0 } NR!=1 { print "b"$0 } { print "c"$0 } END { print "d"$0 }' MyFile
  </code></pre>
