getting list of files and error checking

my @directoryListing = <*.txt *.TXT *.doc *.DOC *.pdf *.PDF>;

Is this a good way of retrieving the list of files in the current working directory?
how would you add error checking to this?

Specifying the extensions the way you have would miss mixed case extensions, such as *.Pdf (if the file system is case sensitive).  Here is a way to not have to deal with that.

You will still need to specify the extensions you want to include.  Just include all of the extensions following the same pattern - I've included .txt, .doc, and .pdf files so far.
my @directoryListing = grep {/\.(txt|doc|pdf)$/i} <*>;

Depends on which errors you want to check.

Given 1 line of code, the only things I can think of, given your code, is to verify that you are in a valid working directory prior to issuing the directory listing, you do that by checking the return value of chdir().

Maybe you had something else in mind, can you clarify?

are there predefined lists I can feed to this file retrieval system?
let's say I wanted to encompass all the possible types of document files or image files, is there a way to do that or do I have to manually enter each extension both lowercase and uppercase?

in terms of error I was wondering wether directory listing would ever be denied to the scirpt
