The system write command takes its message from STDIN, so you can pipe your text into it. The preferred way to do that in perl would be through piped ('magic') open, 

{
    open my $foo, '|-', "/usr/bin/write $user $tty"
        or die $!;
    print $foo 'message here';
    close $foo or die $!;
}

Be cautious how you use this, write is usually regarded as a nuisance, if not an intrusion. The only place it is really accepted is in shutdown messages from root.
