<p>To see what file to invoke the unrar command on, one needs to determine which file is the first in the file set.</p>
<p>Here are some sample file names, of which - naturally - only the first group should be matched:</p>
<pre><code>yes.rar
yes.part1.rar
yes.part01.rar
yes.part001.rar
no.part2.rar
no.part02.rar
no.... | <p>The short answer is that it's not possible to construct a single regex to satisfy your problem. Ruby 1.8 does not have lookaround assertions (the (?<! stuff in your example regex) which is why your regex doesn't work. This leaves you with two options.</p>
<p>1) Use more than one regex to do it.</p>
<pre><code>... | <p>I am no regex expert but here is my attempt</p>
<pre><code>^(yes|no)\.(rar|part0*1\.rar)$
</code></pre>
<p>Replace "yes|no" with the actual file name. I matched it against your examples to see if it would only match the first set hence the "yes|no" in the regex.</p>
