<p style="color: grey"> Python recipe 576582 by <a href="/recipes/users/4168005/">denis</a> (<a href="/recipes/tags/file/">file</a>). Revision 3. </p> <p>openplus() opens pipes and some other objects that quack like files, as well as files:</p> <pre class="prettyprint"><code>| pipe ... -- Popen() a shell <a href="http://" rel="nofollow">http://</a> ftp:// ... -- urlopen() `ls $x`, `geturl web data` -- shell -&gt; filename or url ~/a/b -- sh ls .gz -- gunzip - -- stdin / stdout else -- the builtin open() </code></pre> <p>Users can then read e.g. "| filter data | sort" "| convert ... xx.jpg" "`geturl web data`" like files, just by importing openplus and changing open() -> openplus().</p>
