Launching a shell interactively and manually entering the script line by line is different from launching a shell with a here-document.
I recommend that you either launch the shell with the commands to execute separated by semicolons or that you write out a shell script and launch that shell script from Perl. Both ways are far easier to debug.
Also, I'm not really sure whether your command line is correct. You should launch the shell with sh -c commands... and not sh comands... I think. But then, I avoid such trickery.

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).
