Greetings all,

I'm still a relative Perl newbie, and most of my experience/past projects have been simple parsers. Right now, I have a file listing contained in a file in the following format:

Date (MM-DD-YYYY) \t Time (HH:MM PM) \t Size (in bytes, no formatting) \t Full file path (Directory\filename)

So a sample record would be like:

12-25-2005     12:30 PM     350234     C:\someplace\somefile.txt

What I want to do is sort the list by size, preferably in descending order. I've tried the sort function, and a ST sort, but I get an error on my system that I've run out of memory. This may be because the file I'm using is approximately 400 MB, and I only have 1 GB of memory available.

Any help will be most appreciated. Thank you!

For reference, this is what was used for the last attempt: 

@in = <INPUTFILE>;
@out = map $_->[0] =>
       sort { $a->[1] <=> $b->[1] }
       map [$_, (split(/\t/))[2]] =>
       @in;
