Going from :

    my $notmuch =3D `notmuch show @ARGV`;
    my @filenames =3D ();
    while ($notmuch =3D~ /^\x{0c}message{ .+filename:(.+)$/mg) {
        push @filenames, $1;
    }

to :

    my @filenames =3D split /\n/, `notmuch search --output=3Dfiles @ARGV`;

Thanks, that will clearly enhance my script.
