title: Is there a `sh` equivalent to bash's `<<<' redirection operator?
body: <p>I'm trying to execute an <code>at</code> command from a cgi script.  The script is executed as the default Apache2 user on Ubuntu (<code>www-data</code>) but the default shell is <code>/bin/sh</code> and not <code>bash</code>.   Aside from security issues of running <code>at</code> as <code>www-data</code> (see my other <a href="https://serverfault.com/q/556332/5592">question</a>), I could change the default shell, but I'm wondering, <strong><em>is there a more portable way to write this <code>bash</code> friendly command?</em></strong></p>
  
  <pre><code>at now + 5 minutes &lt;&lt;&lt; 'python my_script.py data_arg'
  </code></pre>
