- unlink LIST

- unlink

  Deletes a list of files. On success, it returns the number of files it successfully deleted. On failure, it returns false and sets `$!` (errno):

          my $unlinked = unlink 'a', 'b', 'c';    unlink @goners;    unlink glob "*.bak";

  On error, `unlink` will not tell you which files it could not remove. If you want to know which files you could not remove, try them one at a time:

           foreach my $file ( @goners ) {         unlink $file or warn "Could not unlink $file: $!";     }

  Note: `unlink` will not attempt to delete directories unless you are superuser and the -U flag is supplied to Perl. Even if these conditions are met, be warned that unlinking a directory can inflict damage on your filesystem. Finally, using `unlink` on directories is not supported on many operating systems. Use `rmdir` instead.

  If LIST is omitted, `unlink` uses `$_` .
