Loop from 1 to 20... (numbers being 1..20)
Well, that, or you can learn to fork in perl.
Basically here is the logic. Loop through all of your sites, and execute the perl script with the argument of what site you want to ftp data to/from, and then throw it in the background to do its thing (so the loop continues). No guarantees it will work, but it should.
I receive files by FTP in an input directory. Every 10 seconds a process checks if some new file has arrived to the input directory and then the process moves them to another directory to be read by a second process.
The problem is that there is no way to know if the download has finished... (11 Replies)

io::async::detachedcode
IO::Async::DetachedCode(3pm) User Contributed Perl Documentation IO::Async::DetachedCode(3pm)NAME
"IO::Async::DetachedCode" - execute code asynchronously in child processes
SYNOPSIS
This object is used indirectly via the "IO::Async::Loop"'s "detach_code" method.
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $code = $loop->detach_code(
code => sub {
my ( $number ) = @_;
return is_prime( $number );
}
);
$code->call(
args => [ 123454321 ],
on_return => sub {
my $isprime = shift;
print "123454321 " . ( $isprime ? "is" : "is not" ) . " a prime number
";
},
on_error => sub {
print STDERR "Cannot determine if it's prime - $_[0]
";
},
);
$loop->run;
DESCRIPTION
This object class provides a legacy compatibility layer for existing code that tries to construct such an object. It should not be used for
new code; see instead the IO::Async::Function object, for which this is now a wrapper.
CONSTRUCTOR
$code = $loop->detach_code( %params )
This function returns a new instance of a "IO::Async::DetachedCode" object. The %params hash takes the following keys:
code => CODE
A block of code to call in the child process.
stream
marshaller
These arguments are no longer used; any values passed will be ignored.
workers => INT
Optional integer, specifies the number of parallel workers to create.
If not supplied, 1 is used.
exit_on_die => BOOL
setup => ARRAY
Passed through to the underlying "IO::Async::Function" object.
METHODS
$code->call( %params )
Calls one invocation of the contained function code block. See the "call" method on "IO::Async::Function" for more detail.
$code->shutdown
This method requests that the detached worker processes stop running.
$n_workers = $code->workers
This method in scalar context returns the number of workers currently running.
@worker_pids = $code->workers
This method in list context returns a list of the PID numbers of all the currently running worker processes.
