-<li>Splitting input into a sequence of <code>records</code>.
-By default split at <code>newline</code> character, but can be changed via the
-builtin <code>RS</code> variable.</li>
-<li>Splitting a <code>record</code> into <code>fields</code>. By default strings without <code>whitespace</code>,
-but can be changed via the builtin variable <code>FS</code> or command line option
-<code>-F</code>.</li>
-</ol>
-<p>Fields are accessed as follows:</p>
-<ul>
-<li><code>$0</code> whole <code>record</code></li>
-<li><code>$1</code> field one</li>
-<li><code>$2</code> field two</li>
-<li>...</li>
-</ul>
-<h2 id="program"><a class="header" href="#program">Program</a></h2>
-<p>An <code>awk</code> program is composed of pairs of the form:</p>
-<pre><code class="language-markdown">pattern { action }
-</code></pre>
-<p>The program is run against each <code>record</code> in the input stream. If a <code>pattern</code>
-matches a <code>record</code> the corresponding <code>action</code> is executed and can access the
-<code>fields</code>.</p>
-<pre><code class="language-markdown">INPUT
-  |
-  v
-record ----&gt; ∀ pattern matched
-  |                   |
-  v                   v
-fields ----&gt; run associated action
-</code></pre>
-<p>Any valid awk <code>expr</code> can be a <code>pattern</code>.</p>
-<p>An example is the regex pattern <code>/abc/ { print $1 }</code> which prints the first
-field if the record matches the regex <code>/abc/</code>. This form is actually a short
-version for <code>$0 ~ /abc/ { print $1 }</code>, see the regex comparison operator
-below.</p>
-<h3 id="special-pattern"><a class="header" href="#special-pattern">Special pattern</a></h3>
-<p>awk provides two special patterns, <code>BEGIN</code> and <code>END</code>, which can be used
-multiple times. Actions with those patterns are <strong>executed exactly once</strong>.</p>
-<ul>
-<li><code>BEGIN</code> actions are run before processing the first record</li>
-<li><code>END</code> actions are run after processing the last record</li>
-</ul>
-<h3 id="special-variables"><a class="header" href="#special-variables">Special variables</a></h3>
-<ul>
-<li><code>RS</code> <em>record separator</em>: first char is the record separator, by default
-<newline></li>
-<li><code>FS</code> <em>field separator</em>: regex to split records into fields, by default
-<space></li>
-<li><code>NR</code> <em>number record</em>: number of current record</li>
-<li><code>NF</code> <em>number fields</em>: number of fields in the current record</li>
-</ul>
-<h3 id="special-statements--functions"><a class="header" href="#special-statements--functions">Special statements &amp; functions</a></h3>
-<ul>
-<li>
-<p><code>printf "fmt", args...</code></p>
-<p>Print format string, args are comma separated.</p>
-<ul>
-<li><code>%s</code> string</li>
-<li><code>%d</code> decimal</li>
-<li><code>%x</code> hex</li>
-<li><code>%f</code> float</li>
-</ul>
-<p>Width can be specified as <code>%Ns</code>, this reserves <code>N</code> chars for a string.
-For floats one can use <code>%N.Mf</code>, <code>N</code> is the total number including <code>.</code> and
-<code>M</code>.</p>
-</li>
-<li>
-<p><code>sprintf("fmt", expr, ...)</code></p>
-<p>Format the expressions according to the format string. Similar as <code>printf</code>,
-but this is a function and return value can be assigned to a variable.</p>
-</li>
-<li>
-<p><code>strftime("fmt")</code></p>
-<p>Print time stamp formatted by <code>fmt</code>.</p>
-<ul>
-<li><code>%Y</code> full year (eg 2020)</li>
-<li><code>%m</code> month (01-12)</li>
-<li><code>%d</code> day (01-31)</li>
-<li><code>%F</code> alias for <code>%Y-%m-%d</code></li>
-<li><code>%H</code> hour (00-23)</li>
-<li><code>%M</code> minute (00-59)</li>

-</ul>
-</li>
-<li>
-<p><code>S ~ R</code>, <code>S !~ R</code></p>
-<p>The regex comparison operator, where the former returns true if the string
-<code>S</code> matches the regex <code>R</code>, and the latter is the negated form.
-The regex can be either a
