Right, this will work with the newest perls (>= 5.6), at least if you use glob() instead of <>.   The problem is: $ ls Hold/* |wc
/bin/ksh: /usr/bin/ls: arg list too long
0 0 0
$ ls Hold |wc
169170 169170 2739945
$ perl -lwe'@x=<"Hold/*">;print 0+@x'
0
$ perl -lwe'@x=glob"Hold/*";print 0+@x'
169170
$
Since 5.6 glob does not use a shell to expand filesystem wildcards.
update:   Gah! tye, of course, is right <Hold/*> is the same as glob"Hold/*".   (No '"'s inside <>.)   p

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).
