<h1> The <tt>s6-sort</tt> program </h1>
<p>
s6-sort sorts its input.
</p>
<h2> Interface </h2>
<pre>
s6-sort [ -b ] [ -c ] [ -f ] [ -r ] [ -u ] [ -0 ]
</pre>
<ul>
<li> s6-sort reads its stdin until EOF </li>
<li> It sorts all the lines it read alphanumerically </li>
<li> It prints the sorted lines to stdout and exits 0 </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-b</tt> : ignore leading spaces and tabs at the beginning of each
line when sorting </li>
<li> <tt>-c</tt> : suppresses normal output, just returns 0 if the output
would have been the same as the input and 1 otherwise </li>
<li> <tt>-f</tt> : ignore case when sorting </li>
<li> <tt>-r</tt> : reverse sort </li>
<li> <tt>-u</tt> : suppresses duplicate lines </li>
<li> <tt>-0</tt> : input and output lines are separated by null characters
instead of newlines </li>
</ul>
<h2> Posixness </h2>
<p>
s6-sort <strong>is not</strong> suitable as a Single Unix
<a href="https://pubs.opengroup.org/onlinepubs/9699919799/utilities/sort.html">sort</a>
program.
