title: One command to create and change directory
body: <p>I'm searching for just <strong>one</strong> command &mdash; nothing with <code>&amp;&amp;</code> or <code>|</code> &mdash; that creates a directory and then immediately changes your current directory to the newly-created directory. (This is a question someone got for his exams of "linux-usage", he made a new command that did that, but that didn't give him the points.) This is on a debian server if that matters.</p>
