For a very flexible approach to renaming see the cookbook, recipe 9.9:
#!/usr/bin/perl -w
# rename - Larry's filename fixer
$op = shift or die "Usage: rename expr [files]\n";
chomp(@ARGV = <STDIN>) unless @ARGV;
for (@ARGV) {
$was = $_;
eval $op;
die $@ if $@;
rename($was,$_) unless $was eq $_;
}
which allows for such nice calling examples as (also from the Cookbook):
% rename 's/\.orig$//' *.orig
% rename 'tr/A-Z/a-z/ unless /^Make/' *
% rename '$_ .= ".bad"' *.f
% rename 'print "$_: "; s/foo/bar/ if <STDIN> =~ /^y/i' *
% find /tmp -name '*~' -print | rename 's/^(.+)~$/.#$1/'

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).
