Reading from a glob into Getopt::Longby biohisham (Priest)

biohisham has asked for the
wisdom of the Perl Monks concerning the following question:
So I have been toying with this concept these few days on my Ubuntu machine using Getopt::Long, what I basically aim to achieve is to pass parameters to the program such as the following:
$perl ReadingMultipleFiles.pl -param1 arg -param2 arg --file *.txtSo my program receives many other options that are strings or integers and I aim to run it on an entire folder of .txt files such that the user has an option of either calling the program on one file by passing the file name in this fashion
$perl ReadingMultipleFiles.pl -param1 arg -param2 arg --file foo.txtor just run it universally on all files via a glob (*) from the STDIN as mentioned above.
Trying various tricks the closer I got to achieving this was through implementing options with multiple values or storing in a hash, however, in both cases, only one file from a group of files is read before the program exits.
I can't think of another way to do this and I don't want to drastically alter my program design so if I can get you to my rescuing esteemed ones it will be awesome.
