title: Finding a unique file
body: <p>Is there a way I can find a unique/modified file?</p>
  <p>I have two text files with hash and names eg:</p>
  <p>file1.txt:</p>
  <pre><code>   c3f2b563b3cb091esada5b40fbfd5e60f526da3d *10.88.10/1.xml
     770aafff757f83e55c4cadaad7144e512299788d *10.88.10/config/2.csv
     38045a78f87addaddada4c3754bea76c72cbfe25 *10.88.10/3.txt
     asddd132dfdada1231431411ddsfadfgdkkgdada *10.88.10/4.js
  </code></pre>
  <p>file2.txt:</p>
  <pre><code>c3f2b563b3cb091esada5b40fbfd5e60f526da3d *10.88.12/1.xml
  770aafff757f83e55c4cadaad7144e512299788d *10.88.12/config/2.csv
  38045a78f87addaddada4c3754bea76c72cbfe25 *10.88.12/3.txt
  asddd1222131231231sadsdaddsfadfgdkkgdada *10.88.12/4.js
  dadadadawqeqweqwg32542362436532wqrewqr32 *10.88.12/5.py
  </code></pre>
  <p>As you can see some of the files in <code>file1.txt</code> and <code>file2.txt</code> are the same. <code>file2.txt</code> has a file added called <code>5.js</code> and an updated/modified file named <code>4.js</code>.</p>
  <p>Is there any way I can output modified and added files in <code>file2.txt</code>?</p>
  <p>Expected Output:</p>
  <pre><code>    10.88.12/4.js
      10.88.12/5.py
  </code></pre>
  <p>I tried the <code>diff</code> command but it shows all files are different because of file name  (10.88.10 to 10.88.12).</p>
  <p>I tried <code>cut -d' ' f1</code> but after the <code>diff</code> command I couldn't find a way to output the file name.</p>
