best way to build an absolute spec

[oldyork90]

I have a directory $my_dir. I test this with -d.
$my_dir is user defined.

I want to build the file spec "$my_dir . $my_fn", but $my_dir may be
constructed as either /one/two or /one/two/.

I could test for the trailing path separator and act accordingly, but is
there a better way, a "standard" or best practice way, of doing this?

How do you pros build the absolute paths?


I find that in Windows "/one/two//my_file" will work, but I'd rather not.

Thanks in advance.

By using one of the several modules that do that job, e.g.

http://search.cpan.org/~smueller/PathTools-3.47/lib/File/Spec.pm

http://search.cpan.org/~dagolden/Path-Tiny-0.054/lib/Path/Tiny.pm

or several others

my $fspec = File::Spec->catfile ($my_dir, $fn);

Works great. Thanks. (changes / to \... hope it doesn't cause any problems.
I grew up with \ as an escape.)

POSIX/ UNIX(*) pathnames may separate two components with any number of
/-characters (subject to pathname lenght limits).
