title: Finding contents of one file in another file
body: <p>I'm using the following shell script to find the contents of one file into another:</p>
  
  <pre><code>#!/bin/ksh
  file="/home/nimish/contents.txt"
  
  while read -r line; do
      grep $line /home/nimish/another_file.csv
  done &lt; "$file"
  </code></pre>
  
  <p>I'm executing the script, but it is not displaying the contents from the CSV file. My contents.txt file contains number such as <code>"08915673"</code> or <code>"123223"</code> which are present in the CSV file as well. Is there anything wrong with what I do?</p>
