From: Jamal Mazrui Date: 2006-04-18T00:37:13+09:00 Subject: Beginner gsub and ri questions How can I do a case-insensitive global substitution? Suppose, for example, a string contained occurences of DOG, Dog, dog, and mistyped dOg. I want every instance to be replaced by cat (without having to test for each case permutation). How can I generate a large text file containing all ri documentation available on my system? I would like the topics to be in as logical an order as possible, and in alphabetical order otherwise. I would like to place a \r\n\f\r\n sepearater sequence between each topic. Jamal
