<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>

<div class="corps">

<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><code class="zsh">grep 'pattern' **/*(.)</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>
|
||
|
||
<div>
|
||
<div class="codefile"><a href="/Scratch/en/blog/02_ackgrep/code/ack">➥ ack</a></div>
|
||
|
||
|
||
<pre><code class="zsh">#!/usr/bin/env zsh
|
||
(($#<1)) && { print 'usage: ack "regexp"' >&2; exit 1 }
|
||
|
||
listeFic=( **/*(.) )
|
||
autoload zargs
|
||
zargs -- $listeFic -- grep $1 | perl -ne 'use Term::ANSIColor;
|
||
if (m/([^:]*)(:.*)('$1')(.*)/) {
|
||
print color("green").$1;
|
||
print color("reset").$2;
|
||
print color("black","on_yellow").$3;
|
||
print color("reset").$4."\n";
|
||
} '
|
||
</code></pre>
|
||
|
||
|
||
</div>
|
||
|
||
<p>For my team and I it is usable enough.
|
||
I hope it could help.</p>
