title: sed strange behaviour when executed inside grave accent - `
body: <p>For some reason I need to escape forward slash inside some string</p>
  
  <pre><code># echo "http://google.com" | sed -e 's/[/]/\\\//g'
  http:\/\/google.com
  </code></pre>
  
  <p>But when I try to execute the same inside `` it shows me:</p>
  
  <pre><code># somevar=`echo "http://google.com" | sed -e 's/[/]/\\\//g'`
  sed: -e expression #1, char 10: unknown option to `s'
  </code></pre>
  
  <p>My sed's version:</p>
  
  <pre><code># rpm -q sed
  sed-4.1.5-8.el5
  </code></pre>
