Though at the risk of the dreaded featuritis, why not
extend this little script to operate in 'suid' mode (with
taint checking, of course) so that regular users can do
stuff without 'sudo' or 'su' such as restart the Apache
server or DNS?
A little 'chmod +s', checking of $< and it might be
that exponentially more useful. Of course, 'suid' mode could
be an option, such that it doesn't explicitly have to
be suid, but if it were, you can be even more lazy.

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).
