Here's a fun trivia task. For an activity I am involved in, I get files from members to process. The filename starts with the member's name and has other info to identify the file. After processing, the file goes in the ./Processed folder. There are thousands of files now in that folder. Right now, I'm looking for a couple basic pieces of information. First, I want to know how many unique names I have in the list. Second, I'd like a list of names and how many files go with each name.
I'm sure this is trivial, but my mind is blanking out on it. A couple simple examples would be nice. Non-answers, like "easy to do with'xxx'" or references to man pages or George's Book, etc. are not helpful right now. Thanks, Michael
