Script to increment number in a file
<p>I have one file like below,let say file name is file1.txt:</p>

<pre><code>s.version      = "11.7.10"
</code></pre>

<p>Here I have to increment the last number by 1, so it should be 1+1=2 like..</p>

<pre><code>s.version      = "11.7.11"
</code></pre>

<p>Is there any way for this. Thanks in advance.</p>
