<p>As <a href="">Andy Lester</a> told me <a href=""><code>ack</code></a> is a simple file you only have to copy in your <code>~/bin</code> folder. Now I’ve got <code>ack</code> on my professional server.</p>
<p>Go on <a href=""></a> to download it.</p>
<p>Sincerely, I don’t understand <code>ack</code> don’t become a common command on all UNIX systems. I can no more live without. For me it is as essential as <code>which</code> or <code>find</code>.</p>

<h1 id="better-than-grep">Better than grep</h1>
<p>One of the my main usage of <code>grep</code> is</p>
<div class="sourceCode" id="cb1"><pre class="sourceCode zsh"><code class="sourceCode zsh"><a class="sourceLine" id="cb1-1" title="1"><span class="kw">grep</span> <span class="st">'pattern'</span> **/*<span class="kw">(.)</span></a></code></pre></div>
<p>Most of time it is enough. But it is far better with colored output. <code>ack-grep</code> in Ubuntu does that. As I couldn’t install it on my ‘Evil Company Server’, I had done one myself in very few lines:</p>
<pre><code>#!/usr/bin/env zsh
(($#&lt;1)) &amp;&amp; { print 'usage: ack &quot;regexp&quot;' &gt;&amp;2; exit 1 }
listeFic=( **/*(.) )
autoload zargs
zargs -- $listeFic -- grep $1 | perl -ne 'use Term::ANSIColor;
if (m/([^:]*)(:.*)('$1')(.*)/) {
print color(&quot;green&quot;).$1;
print color(&quot;reset&quot;).$2;
print color(&quot;black&quot;,&quot;on_yellow&quot;).$3;
print color(&quot;reset&quot;).$4.&quot;\n&quot;;
} '</code></pre>
<p>For my team and I it is usable enough. I hope it could help.</p>
