Your regular expression does match because it is really present inside the string:
"[someRandomName]." (The text in bracket is the matched text)
"[someRandomName]-"
What you want is anchoring the regular expression. Try adding a '^' at the beginning and a '$' at the end of the regular expression. The Regex will then try to match against the whole string, and not only on a part of it:
/^[A-Z0-9]+[A-Z0-9-]+[A-Z0-9]{1}$/i
Hope this helps. See perlre for more infos about this
#!/usr/bin/perl -w
use strict;
my $domain = $ARGV[0];
print "Got $domain\n";
if ($domain =~ /^[A-Z0-9]+[A-Z0-9-]+[A-Z0-9]$/i)
{
print "$domain matched\n\n";
}
else
{
print "$domain did not match\n\n";
}
__END__

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).
