title: Script or command to increment number in file name inside file
body: <p>I have a file in which we have entries in following format. I would like to increment the numbers in file names inside this file. So <code>some_v1.png</code> will become <code>some_v2.png</code>. Is there a way with regex OR command line utility to achieve this.</p>
  
  <p>Following is example file (file.config) with file entries as string.</p>
  
  <pre><code>something/some_v1.png
  something/some_v4.png
  something/some_v3.png
  </code></pre>
