My code above pretty well does this without shelling out:

use warnings;
use strict;

my @lines = (
    "myserver.it.ca. XXXX XXX XXX XXXXXXXXXXX",
    "myserver.it.org. XXXX XXX XXX XXXXXXXXXXX",
    "myserver.it.com. XXXX XXX XXX XXXXXXXXXXX",
);

for my $line (@lines){
    my $server = (split /\s+/, $line)[0];
    $server =~ s/\.$//;
    print "$server\n";
}

__END__
myserver.it.ca
myserver.it.org
myserver.it.com
