title: Deleting multiple lines from a csv file using sed
body: <p>I am just learning to work with csv files from the command line. I want to delete several lines from a file using <code>sed</code>. I've removed the header of a file with this <code>cat file.csv | sed 1,2d &gt; file.csv</code>.</p>
  
  <p>Now I want to delete several more lines from the file (lines 3, 10, 12, and 28-35) and I am not sure how to pull it off. I'd be grateful for any help.</p>
