title: Comparing checksums from a directory and checksums from a store.txt file line by line to see if changes were made
body: <p>I am facing a problem with my bash script whereby I need to compare the checksums of my backup files from my /axa/backup/ directory and the store.txt file in which I have stored my checksums in to make sure that no changes have been made. I am required to use a for loop and a if-else loop but it seems to not work as I seldom use it.</p>
  
  <p>This is my bash script that I have written:</p>
  
  <pre><code>#!/bin/bash
  for md5sum in /sads/backup/*.tgz
  do
    if [ "md5sum" = cat store.txt ]
    then 
       echo "no changes made in /sads/backup/*.tgz "
    else
       echo "Changes made in /sads/backup/*.tgz "
    fi
  done
  </code></pre>
