title: How would I go about creating a flow chart representing a linux grep command?
body: <p>I am currently using the Linux terminal and command:</p>
  
  <pre><code>cat [filename] | grep [searchword]
  </code></pre>
  
  <p>To search a file contents for a specific word/string, but how would i represent this command within a flow chart? Would I use a parallelogram shape to show an input of the cat output into the grep command?
  Any ideas? thanks</p>
