help: downloading online files with perl

#1 December 24th, 2006, 09:25 PM

Hi,
I am trying to write a script that downloads a file from a website everyday.
Can I just use the copy command (i.e. use File::Copy)? Does it support URI?
I wrote something like below, but it does not seem to work.

use File::Copy;
copy(www.abc.com\abc.pdf, "C:\myfolder\") or die "File cannot be copied.";

Is there a better way to do this?

Sorry, it seems like a very easy thing to do, but I am doing something
wrong...

Thank you

Your Question is Asked Frequently:
"How do I fetch an HTML file?"

No.

Well, of course not. A URI can be anything, not just a simple file.

Yes. As explained in the FAQ.

Have a look at LWP (lib-www-perl). You'll probably need to do an HTTP
request, but it supports ftp, gopher and local file systems using this
module. I haven't tried this with what you're trying to do so I don't have
any examples, but I have used LWP to retrieve HTTP pages.
