in reply to How to use file copy with wild card characters

What if the wildcarded filename matches more than one file? What is the expected behavior?

    File::Copy won't function without a $to and $from argument, so some naming convention for the new files is needed. I would approach it in this manner:

    map { copy($_, $_ . '.new') } glob("*.ext");

      While I agree that that is probably a good idea, it doesn't answer the question that I asked. It could be that the OP only wants to save one archived log. So, in that case, you could move every file in the glob to a static file name i.e. 
      foreach my $file (glob('*.log')) {
   rename $file, "oldlog" or die "Oops: $!";
}

      Danger, Will Robinson! map in void context! I would write that like this instead:

      copy($_, "$_.new") for glob "*.ext";

      I think it's much easier to look at.
