Pulling file name from path

I've written a 'create_sql_table' routine which starts off by =
pulling
the file name (sans suffix) from a path. I've posted four code snippets =
below.
All work fine, but I'm curious to know if there is a better (or more =
elegant) way
to do it?

The second example is one line shorter than the first and =
doesn't populate
an array to get the job done. Would that make it more efficient?

Considering the last two examples, I like File::Basename more. =
However,
is there any overhead using a module like this as opposed to the first =
two examples?

Or is there a better way that I haven't run across yet? It =
needs to be
multi-platform.

Thanks,
Marc


my $file_path =3D "../htdocs/_carts/sql/data/orders.tsv";
my @words =3D split (/\//, $file_path);
(my $file_name =3D $words[-1]) =3D~ s/\.[^.]+$//; # $filename =3D =
orders

my $file_path =3D "../htdocs/_carts/sql/data/catalog.tsv";
(my $file_name =3D substr($file_path, rindex($file_path,"/") + 1, =
length($file_path)-rindex($file_path,"/") - 1)) =3D~ s/\.[^.]+$//;

use File::Spec;
my $file_path =3D "../htdocs/_carts/sql/data/categories.tsv";
my ($volume, $directories, $file_name) =3D =
File::Spec->splitpath($file_path);

use File::Basename;

my $filename =3D fileparse($file_path, qr/\.[^.]*/); # $filename =3D =

Use File::Spec and File::Basename together. They offer platform
independence.

use File::Spec;
use File::Basename;

my $file_path = "../htdocs/_carts/sql/data/categories.tsv";
my ($volume, $directories, $file_name) =
File::Spec->splitpath($file_path);
my $filename = fileparse($file_name, qr/\.[^.]*/); # $filename =
customers

=46rom what I read, I thought they did the same thing, but from =
your post it appears that there may be differences. What's the =
advantage in using both instead of one or the other? Are they not =
platform independent on their own? I've only been able to run tests on =
a Mac.

File::Spec::splitpath() does not parse the suffixes.

File::Basename::parsefile() does not parse the volume.

What you use depends on your application's needs.
