suppressing stat/newline warning

superpete has asked for the wisdom of the Perl Monks concerning the following question:

In my quest to make my code support completely arbitrary filenames, I think i've succeeded.

But I have uncovered a new issue. Whenever a "-X" test returns a negative result, and the filename happens to have a newline in it (newlines are valid in unix filenames), perl issues a "Unsuccessful stat on filename containing newline" warning. (if we're running perl -w)

According to the perldiag manpage, perl thinks I forgot to chomp my filename. But what if the filename really has a newline in it? 

-e "$dir/foo"
   or mkdir "$dir/foo"

[download]

If $dir happens to have a newline in it, the code results in a warning :-(

What to do? Is there a way to suppress that one specific warning?

    In old perl you can't be so specific, but in 5.6+ you can say:

    {
    no warnings 'newline';
    -e "${dir}/foo" or mkdir "${dir}/foo";
}
