Do you want to do any additional processing while the file is being transferred? If not, I don't see why the transfer process should be separated from the main process.

Otherwise, here's a small script on how to use fork:
Code:
#!/usr/bin/perl -w

use strict;
use warnings;

print "Parent script\n";

my $pid = fork();
if ( $pid == 0 ) {
    print "Child script started\n";
    sleep 5;
    print "Child script ending\n";
    exit int( rand(255) );
}
elsif ( $pid > 0 ) {
    print "Parent script, child has PID $pid\n";
    waitpid( $pid, 0 );
    print "Parent script, child exited with status " . ( $? / 256 ) . "\n";
    exit 0;
}
else {
    print "Error when forking: $!\n";
}
