title: unset a function for one line in a bash script
body: <p>In a script, I've defined: <code>rm() { echo "rm $@" }</code></p>
  
  <p>Normally <code>rm</code> would run <code>echo rm</code>, but I want to change it for a single line to run the actual <code>rm</code> command. How can I do this? </p>
  
  <p>I've tried:</p>
  
  <p><code>rm= rm file</code> but this still runs <code>echo rm file</code>  </p>
  
  <p>I don't want to <code>unset rm</code> because I still want to be able to run <code>rm file</code> and expect it to echo.</p>
  
  <p>Note: <code>rm</code> is just an example command, not the command I'm actually using. </p>
