Under what conditions and/or for what goals (if any!) would a shell script (csh, bash, dos-batch etc.) be more appropriate than a perl script?
Update (Sep 29, 07): People have been wondering if this is a homework question: it isn't. Recently, my hard-drive crashed and I am working on a periodic data archival scheme using rsync and cdrtools. I have been successfully rsync'ing by hand. Since the planned automated script would be calling rsync and cdrtools -- which in turn would be interacting with the OS to work with the file-system -- I was wondering if it would be safer to stay close to the OS and use batch files rather than perl. Such is the motivation for this question.

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).
