title: Apply regex on columns using awk
body: <p>I have the following string that I get:</p>
  
  <pre><code> new Field("count").del("query_then_fetch");
   new Field("scan").del("query_then_fetch sorting on `_doc`");
   new Field("compress").del("no replacement, implemented at the codec level");
   new Field("compress_threshold").del("no replacement");
   new Field("filter").del("query");
  </code></pre>
  
  <p>I run the following script on command line where the regex matches the strings that are in double quotes.:</p>
  
  <pre><code>awk -F '.del' '{match($1, "\".*\"", a); match($2, "\".*\"", b)}END{print a[0]; print b[0]}'
  </code></pre>
  
  <p>expecting this king of output:</p>
  
  <pre><code>"count" "query_then_fetch"
  "scan" "query_then_fetch sorting on `_doc`"
  "compress" "no replacement, implemented at the codec level"
  "compress_threshold" "no replacement"
  "filter" "query"
  </code></pre>
  
  <p>but instead I get this output:</p>
  
  <pre><code>"filter"
  "query"
  </code></pre>
  
  <p>How to resolve this issue?</p>
