title: Remove extra characters from diff output
body: <p>I have the below output from unix:</p>
  <pre><code>$ diff -y --suppress-common-lines backup.txt newfile.txt
                                                                &gt; `jjj' int,
  </code></pre>
  <p>i need only jjj : int as output.
  tried the below didnt work as expected:</p>
  <pre><code>$ diff -y --suppress-common-lines backup.txt newfile.txt | grep -i '&gt;' |tr -d '[&gt;]'  |sed 's/,//g'
  </code></pre>
