Edit Question
Title
Body
I have a file with 450,000+ rows of entries. Each entry is about 7 characters in length. What I want to know is the unique characters of this file. For instance, if my file were the following; Entry ----- Yabba Dabba Doo Then the result would be Unique characters: {abdoy} Notice I don't care about case and don't need to order the results. Something tells me this is very easy for the Linux folks to solve. Update I'm looking for a very fast solution. I really don't want to have to create code to loop over each entry, loop through each character...and so on. I'm looking for a nice script solution. Update 2 By Fast , I mean fast to implement...not necessarily fast to run.
