title: substitution operator :s in VIM in unix
body: <p>In unix,  while using VIM and the substitue command  I am unable to replace the value to a string containing special character <code>/</code></p>
  <pre><code> :%s/var1/&quot;ab1/ab2/ab3&quot;/g
  </code></pre>
  <p>I need to replace the entire file containing <code>var1</code> with <code>ab1/ab2/ab3</code></p>
  <p>Output in vim I see: <code>Trailing characters</code></p>
