title: how to replace a part of string when it contains a metacharacter in perl
body: <p>I have strings that look like this for example <code>subnet 1 ims-0-x ip address</code></p>
  
  <p>and I want to get rid of the <code>-x</code> so it will be <code>subnet 1 ims-0 ip address</code></p>
  
  <p>I tried doing this regex replace</p>
  
  <pre><code>$string=~ s/\\-x//;
  </code></pre>
  
  <p>which is not working. I think my issue is that I am not escaping the dash properly. please help me fix that one line.</p>
