- I was never able to find a decent piece of code that was able to parse out the extension of a given file delimited by a '.' regardless of how many '.'s were in the filename
While I do admire your industrial spirit, you can already do this with File::Basename ...
use File::Basename;
my $fname = "/usr/local/isp/system.update.perl";
my ($name, $path, $suffix) = fileparse($fname, '\.[^\.]*');
print STDOUT $name, "\n";
The key to this working is the regular expression passed to the fileparse method - The regular expression in the example above matches the suffix of a file as being the last dot and what follows it, excluding any subsequent dots ([^\.]).
perl -e 's&&rob@cowsnet.com.au&&&split/[@.]/&&s&.com.&_&&&print'

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).
