Take a look at LWP::Simple's (alt.) `getstore` or `mirror` functions. `my $url = 'http://www.db.ucsd.edu/publications/xkeyword.pdf'; my $file = 'xkeyword.pdf'; unless ( is_success( mirror($url, $file) ) ) { warn "Couldn't download $url\n"; }` [download] --k.	[reply] [d/l] [select]

A non Perl answer, and if your running Linux would be the wget command. `wget -r www.db.ucsd.edu/publications/`	[reply] [d/l]

Thanks a lot. I also found mirror function in Perl Cookbook. Here I have a concern. Since I want to download huge number of files, will the mirror function be a little bit slow? Is there a faster way to do it? Xuehua	[reply]

The bottleneck is the bandwidth between your site and the target, NOT the code that does the download which is essentially just setting up a socket, sending a GET /publications/some.pdf HTTP/1.1 line and then grabbing the results off the socket. It will make no real speed difference what you use. But as noted I would tend just to use wget unless I had specific reasons to do it in Perl. cheers tachyon s&&rsenoyhcatreve&&&s&n.+t&"$'$`$\"$\&"&ee&&y&srve&&d&&print	[reply]
