The whole program is a bit complex and does a bunch of stuff that isn't relavent to this issue, but I've cut out everything but this section that shows the problem I'm having.
#!/usr/bin/perl -w
use strict;
my @h = ( qw(
psapp1
psapp
psapp2
psepapp1
psepapp
psepapp2
psimgprod
pspappuat
pswebapp2
pswebapp
) );
my @h_sorted = @h[
map { unpack "N", substr($_,-4) }
sort
map {
my $key = $h[$_];
$key =~ s[(\d+)][ pack "N", $1 ]ge;
$key . pack "N", $_
} 0..$#h
];
foreach (@h_sorted) { print "$_\n"; };
When I run this program, with my Perl (This is perl, v5.8.6 built for darwin-thread-multi-2level), I get:
psapp
psapp1
psapp2
psepapp1
psepapp2
psepapp
psimgprod
pspappuat
pswebapp2
pswebapp
The "psapp" items sort properly, but the "psepapp" and "pswebapp" ones show the problem I'm asking about.
Thanks!

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).
