Recursive Directory Listing</h2><p>You probably won't need <a name="INDEX-875" />recursive directory access for the firstfew dozen hours of your Perl programming career. So rather thandistract you with the possibility of replacing all those ugly<i class="command">find</i> scripts with Perl right now, we'llsimply entice you by saying that Perl comes with a nice librarycalled<a name="INDEX-876" /><tt class="literal">File::Find</tt>, which you can use for nifty recursivedirectory processing. We're also saying this to keep you fromwriting your own routines, which everyone seems to want to do afterthose first few dozen hours of programming, and then getting puzzledabout things like "local directory handles" and"how do I change my directory back?" So, whenyou're ready, the knowledge will come, but stay with us tolearn about Manipulating Files and Directories (in the next chapter)instead, right after you finish these exercises.<a name="INDEX-877" /></p><hr width="684" align="left" /><div class="navbar"><table width="684" border="0"><tr><td align="left" valign="top" width="228"><a href="ch12_04.htm"><img alt="Previous" border="0" src="../gifs/txtpreva.gif" /></a></td><td align="center" valign="top" width="228"><a href="index.htm"><img alt="Home" border="0" src="../gifs/txthome.gif" /></a></td><td align="right" valign="top" width="228"><a href="ch12_06.htm"><img alt="Next" border="0" src="../gifs/txtnexta.gif" /></a></td></tr><tr><td align="left" valign="top" width="228">12.4.
