Okok my bad, sorry. I had a feeling I wasn't asking my question right, but I couldn't put my finger on it--but you've shown me the problem. What I'd like to do is 'sudo su' or 'sudo bash' and execute system calls within that environment.
It's not quite as asinine as it sounds--it's just the limitations I find myself working under, and it's simply not possible for me to change the environment. Actually I suppose it is a bit asinine, but I'm still intensely curious if it's possible without Expect.
It's come up in other situations as well, such as automating tasks via Net::OpenSSH needing privilege escalation--or sudo with a password over the connection, where I need to issue a series of commands where the output of one command will determine some of the syntax of the next one. So I can't very easily just chain them up with &&'s.

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).
