How to solve a complex statistics problem with a script?

In this game, you roll a number of six-sided dice to get a total. The total is either the highest single die result, or the sum of any multiples rolled, whichever is higher. For example: If I roll three dice and get a 3, 4, and 6, my total is 6. But if I roll a 4, 4, and 6, my total is 8, the sum of the two 4s. What I want to find out is the mean, median, mode, and standard deviation of the possible totals given N dice. How might I create a simple script to compute this? [more inside]

Shell script handling CSV columns

Joining MP3 Files Together Based on Date in Filename?

I have a podcast that downloads as multiple segments over multiple days. Its format arrives as YYYYMMDD_showcode_segment.mp3; so, for example, one download might result in files as 20090323_goofa_01.mp3 through 20090323_goofa_21.mp3, and also within the same download 20090324_goofa_01.mp3 through 20090324_goofa_21.mp3. What I'm looking for is a Unix script (shell, perl, what have you) that would look at a directory and look at what dates are represented there, and let me join all of the segments together by day. I can use mpgtx -j to do the actual joining; I'm looking for the code that would let the script determine what dates are in the directory and then get each day's segments united into a single MP3 for that day's show.

datascrubbing: I'm using rm -R */*.gif (for example) to get rid of unnecessary files in a directory. There is stuff that's nested about five directories deep that I can't get to using the above command. I'm using the Bash terminal in OS X. specifically, there is a redundant file called "popup" nested in there that I want to get rid of, among others.

Second related problem: is there a way to recursively delete (full) directories, say ones that end in .blob using wildcards? And would I use rmdir or rm -R to do this?

I'm working on a copy of the original, so its ok to experiment a little
