title: bash to beep if command takes more than 1 minute to finish
body: <p>I'm looking for my bash  to beep, if the command i execute take more
    than a certain wall time ( say 1 minute ).</p>
  
  <p>if it keeps on beeping every few minutes there after till i hit enter
    or something .. that's greate.</p>
  
  <p>Any clever ideas ?  </p>
  
  <p>I can use screen's monitor function as last resort.
    (I'm on cygwin, but that shouldn't matter ).</p>
  
  <p>Let me clarify:</p>
  
  <pre><code> $ ls    
     &lt; output appears &gt;   
   $ rsync foo bar 
     &lt; since this takes lot of time, i switch to other console
        and forget this .. .and remember only after some time &gt;
      &lt; so when this finished, i want it to beep &gt;
  </code></pre>
