title: sed error: unterminated 's' command
body: <p>I run below sed command</p>
  
  <pre><code>sed -i s/abc=.*$/abc=def ghi/g hpq_sf_attach_wf_param.txt
  </code></pre>
  
  <p>and it gave me error:</p>
  
  <pre><code>sed: -e expression #1, char 17: unterminated `s' command
  </code></pre>
  
  <p>I noticed it is due to space in between of <code>def</code> and <code>ghi</code>.
  Any idea how to fix it?</p>
