title: Command line tool to search docx file under ms dos or cygwin
body: <p>Is there a command line tool that is able to search docx file under ms dos or cygwin ?</p>
  
  <p>I have tried grep, it's not working with docx while working fine with txt file.</p>
  
  <p>I know I could always convert the docx to txt 1st then search using grep, but I am wondering </p>
  
  <p>is there a command tool that I can search directly under command line?</p>
  
  <p>Thanks</p>
