title: Print filenames & line number with number of fields greater than 'x'
body: <p>I am running Ubuntu Linux. I am in need to print filenames &amp; line numbers containing more than 7 columns. There are several hundred thousand files.</p>
  <p>I am able to print the number of columns per file using awk. However the output I am after is something like</p>
  <p><code>file1.csv-463</code> which is to suggest file1.csv has more than 7 records on line 463. I am using awk command <code>awk -F&quot;,&quot; '{print NF}' *</code> to print the number of fields across all files.</p>
  <p>Please could I request help?</p>
