IO::All::FTP(3pm)					User Contributed Perl Documentation					 IO::All::FTP(3pm)

NAME
IO::All::FTP - Extends IO::All to FTP URLs SYNOPSIS
use IO::All; "hello world " > io('ftp://localhost/test/x'); # save to FTP io('ftp//example.org/pub/xyz') > io('xyz'); # GET to file # two ways of getting a file with a password: $content < io('ftp://me:secret@example.org/xyz'); $content < io('ftp://example.org/xyz')->user('me')->password('secret'); DESCRIPTION
This module extends IO::All for dealing with FTP URLs. Note that you don't need to use it explicitly, as it is autoloaded by IO::All whenever it sees something that looks like an FTP URL. METHODS
This is a subclass of IO::All::LWP. The only new method is "ftp", which can be used to create a blank IO::All::FTP object; or it can also take an FTP URL as a parameter. Note that in most cases it is simpler just to call io('ftp//example.com'), which calls the "ftp" method automatically. OPERATOR OVERLOADING
The same operators from IO::All may be used. < GETs an FTP URL; > PUTs to an FTP URL. SEE ALSO
IO::All::LWP, IO::All, LWP. AUTHORS
