<p>So I'm looking for a pattern like this:</p>

<blockquote>
  <p>size='0x0'</p>
</blockquote>

<p>In a log file, but I'm only interested in large sizes (4 digits or more). The following regex works great in EditPadPro (nice tool BTW)</p>

<pre><code>size='0x[0-9a-fA-F]{4,}
</code></pre>

<p>But the same RegEx does not work in awk - seems like the repetition <code>{4,}</code> is messing it up. Same with WinGrep - any idea from the RegEx gurus? Thanks!</p>

I don't know of any elegant alternatives to the {4,} syntax, but if it is not working in your desired environment you could resort to this ugly hack:
```
```
size='0x[0-9a-fA-F][0-9a-fA-F][0-9a-fA-F][0-9a-fA-F]+
```
```
Hope this helps!
