Do any of you know what command(s) I should use if I want to compare 2 files, to see what the differences are? say for example i have file 1 that contains the words dog and cat, in that order and file2 that has cat, mouse, dog, in that order what I want it to tell me is that the only difference is that file 2 has mouse, so regardless of order. i know diff is supposed to do something like this, but I want to know the file differences even if they aren't sorted. Thanks. Lorne
