I have "spreadsheet-like" data that looks like this: a1 b1 c1 a2 b2 c2 a3 b3 c3 and I want to get it in a form like: a1 a2 a3 b1 b2 b3 c1 c2 c3 Before I re-invent the wheel, does anyone have anything that will do this? Is there perhaps a unix tool that does this sort of thing? Email preferred. Thanks, -Rob
