title: How can I filter out specific column from a CSV file in Perl?
body: <p>I am just a beginner in Perl and need some help in filtering columns using a Perl script.
  I have about 10 columns separated by comma in a file and I need to keep 5 columns in that file and get rid of every other columns from that file. How do we achieve this? </p>
  
  <p>Thanks a lot for anybody's assistance. </p>
