Re^2: Use of foreach

And that undefined element should be (at least) the first in the array, because the OP only tries to print the first element (and then exits):

foreach (@file_names){
    print $_; exit;
}

I guess the `exit;` is there to track where something goes wrong at a particular line. I prefer to put `die 'OK';` somewhere before/after suspected lines, whenever I'm in hard time debugging code. The program will be instantly death with calming message: `OK at __FILE__ line __LINE__`. Open source softwares? Share and enjoy. Make profit from them if you can. Yet, share and enjoy!
