Anonymous Monk,

If you are using the Net::FTP module you want to use the cwd method. The following example is from the documentation

use Net::FTP;

$ftp = Net::FTP->new("some.host.name", Debug => 0)
  or die "Cannot connect to some.host.name: $@";

$ftp->login("anonymous",'-anonymous@')
  or die "Cannot login ", $ftp->message;

$ftp->cwd("/pub")
  or die "Cannot change working directory ", $ftp->message;

$ftp->get("that.file")
  or die "get failed ", $ftp->message;

$ftp->quit;

Should you need information on how to install modules, check out Installing Modules from the Tutorials section of this site.

Update: Please read the PerlMonks FAQ and How do I post a question effectively? if you have not done so already. The title and the content of your post could be a lot better.

hope this helps.
