You have received some good answers based on the info you have given. Unfortunately, that info has been incomplete or contradictory and has caused considerable wasted motion (and a bit of evident frustration) on the part of your fellow monks. What we'd like to know is something like this: for a typical string defined thusly
abcd1_abc_123456.abc1a_A.201307282200-2300-12.gz
field A ---^^^^^^^^^^^^ ^^--- field B
fixed width? variable width!
fixed offset? fixed offset?
sort first (numerically? ascending?) by field X, then sort (numerically? ascending?) by field Y.
A mind is a terrible thing to waste. Please think before you post!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
