Hello all,

I have tried the first solution posted, which was similar to what 

my ($input_root) = ($input_file =~ /([^\\\/]+)\.\w+$/);
open(IN,     "<$input_file")  or die "Couldn't open file: $!: $input_f
+ile";
while(<IN>) {
  if (/\r\n/) { die "DOS files not allowed" }
  $total_lines++;
}

When I run a DOS file through this code it does not "die" on me. See the problem is that I built a validation program that validates UNIX text files. Sometimes when people hand-edit the file they save it in a DOS format via UltraEdit. We don't find out that we sent a DOS file until our Vendor tries to ingest it, which is a pain in the butt.

That is my situation and code. Any help would be appreciated. I spot check files by hand and do convert them to UNIX via perl, but I want really to return an error that stop validation so the user will fix the file to UNIX.

Thanks,
fritzvtb
