<h1> The <tt>s6-tail</tt> program </h1>
<p>
s6-tail prints a file or its stdin after a certain number of bytes or lines.
</p>
<h2> Interface </h2>
<pre>
s6-tail [ -n <em>lines</em> | -c <em>chars</em> ] [ <em>file</em> ]
</pre>
<p>
s6-tail acts as the generic
<a href="https://pubs.opengroup.org/onlinepubs/9699919799/utilities/tail.html">tail</a> utility,
except that the <strong>-f</strong> option is not supported.
</p>
<h2> Posixness </h2>
<p>
s6-tail <strong>is not</strong> suitable as a Single Unix
<a href="https://pubs.opengroup.org/onlinepubs/9699919799/utilities/tail.html">tail</a>
program; however, if you are never using the <tt>-f</tt> functionality, s6-tail
scrupulously follows the rest of the specification.
