</dd>
<dt><code>--compress-program=&lt;PROG&gt;</code></dt>
<dd>
<p>compress temporary files with PROG, decompress with PROG -d; PROG has to take input from stdin and output to stdout</p>

<dd>
<p>Merge at most N_MERGE inputs at once.</p>

<p>read input from the files specified by NUL-terminated NUL_FILES</p>

<p>The key format is <code>FIELD[.CHAR][OPTIONS][,FIELD[.CHAR]][OPTIONS]</code>.</p>
<p>Fields by default are separated by the first whitespace after a non-whitespace character. Use <code>-t</code> to specify a custom separator.
In the default case, whitespace is appended at the beginning of each field. Custom separators however are not included in fields.</p>
<p><code>FIELD</code> and <code>CHAR</code> both start at 1 (i.e. they are 1-indexed). If there is no end specified after a comma, the end will be the end of the line.
If <code>CHAR</code> is set 0, it means the end of the field. <code>CHAR</code> defaults to 1 for the start position and to 0 for the end position.</p>
<p>Valid options are: <code>MbdfhnRrV</code>. They override the global options for this key.</p>
<h2 id="examples"><a class="header" href="#examples">Examples</a></h2>
<p>Sort a file in ascending order:</p>
<pre><code class="language-shell">sort {{path/to/file}}
</code></pre>
<p>Sort a file in descending order:</p>
<pre><code class="language-shell">sort --reverse {{path/to/file}}
</code></pre>
<p>Sort a file in case-insensitive way:</p>
<pre><code class="language-shell">sort --ignore-case {{path/to/file}}
</code></pre>
<p>Sort a file using numeric rather than alphabetic order:</p>
<pre><code class="language-shell">sort --numeric-sort {{path/to/file}}
</code></pre>
<p>Sort <code>/etc/passwd</code> by the 3rd field of each line numerically, using &quot;:&quot; as a field separator:</p>
<pre><code class="language-shell">sort --field-separator={{:}} --key={{3n}} {{/etc/passwd}}
</code></pre>
<p>Sort a file preserving only unique lines:</p>
<pre><code class="language-shell">sort --unique {{path/to/file}}
</code></pre>
<p>Sort a file, printing the output to the specified output file (can be used to sort a file in-place):</p>
<pre><code class="language-shell">sort --output={{path/to/file}} {{path/to/file}}
</code></pre>
<p>Sort numbers with exponents:</p>
<pre><code class="language-shell">sort --general-numeric-sort {{path/to/file}}
</code></pre>
