I've created a sub-routine to run a command so I can test it out with the timethese routine

however when it runs it outputs
sh: | ./perl/tester.pl: No such file or directory
the file is there but I can't figure out what's wrong

sub run {
    # creates data
    my $conf = `(cat ./BasicTest.opt; ls ./data/*_seq.xml)`;
    my $num = shift;

    # changes a setting
    $conf = s/99/$num/;

    # runs program
    return `"$conf | ./perl/tester.pl"`;
}
