perl -e'print"$_\n"for glob("{00,20,40,60,80,A0,C0,FF}"x3);'
Update: trimmed a dozen chars thanks to
CheeseLord
perl -le'print for glob"{00,33,66,99,CC,FF}"x3'
Update 2: I don't fully understand the meat of this myself (i think it came from
tilly) If anyone knows
how this works, I'd actually love an explanation, especially since the
glob docs aren't very helpful.
Update 3: Indeed it was tilly that showed me this trick. Original node at Re (tilly) 2: Sort of like a file handle, but not.

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).
