<p>As <a href="http://www.theworkinggeek.com">Andy Lester</a> told me <a href="http://betterthangrep.com"><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="http://betterthangrep.com">http://betterthangrep.com</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 class="first" id="better-than-grep">Better than grep</h1>
|
||
|
||
<p>One of the my main usage of <code>grep</code> is</p>
|
||
|
||
<div>
|
||
<pre class="twilight">
|
||
grep <span class="String"><span class="String">'</span>pattern<span class="String">'</span></span> **/*(.)
|
||
</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>
|
||
|

<div>
|
||
<div class="code"><div class="file"><a href="/Scratch/en/blog/02_ackgrep/code/ack"> ➥ ack </a></div><div class="withfile">

|
||
|
||
listeFic=( **/*(.) )
|
||
autoload zargs
|
||
zargs -- <span class="Variable"><span class="Variable">$</span>listeFic</span> -- grep <span class="Variable"><span class="Variable">$</span>1</span> <span class="Keyword">|</span> perl -ne <span class="String"><span class="String">'</span>use Term::ANSIColor;</span>

<span class="String"> print color("green").$1;</span>

<span class="String"> print color("reset").$2;</span>

</pre>

</div></div>

|

|

<p>For my team and I it is usable enough.

I hope it could help.</p>
