You can try:
$path = 'd:/ab/c/de/fgh/file.txt';
my $filename = (split(/\//,$path))[-1];
printf "%-s\n", $filename;
which prints
file.txt
Wags ;)

I think what you're looking for is something like this:
my $filename = split(/\//,$path)[7]; #assuming you want the seventh item
I don't know how you would get the last one if you didn't know how many
there were, though.

Subject: Returning one item out of a list
Hey all,
I seem to remember seeing this done somewhere, but now I can't figure
out
how to do it now.
If you have a function that returns a list, such as split(), is there a
way
to only return one item from that list, as if you were working with an
array?
For instance, if you have something like this:
my $path = '/big/long/path/to/something.txt';
my @dirs = split(/\//,$path);
my $filename = $dirs[$#dirs];
Is there a way to eliminate the storing of each directory in @dirs, and
just
assign $filename straight to the last item of what split() returns? I'm
not
sure if it can be done, and if it can, I'm probably overlooking
something
obvious... either way, I can't figure it out.
Thanks,

Michael
