<p><a href="https://github.com/sni" class="user-mention">@sni</a> you should understand how shell parser works. wc and grep are not ran under sudo, they are next command in pipe chain, if <em>want</em> them to run under sudo, you must prepend sudo to each of them</p>

<p>why it works is likely "ip" command does not require root access, and sudo will just include <code>/sbin</code> in path so the program is visible. solution: use abs path.</p>
