Yeah, for this sort of thing, you really need to have the data sorted (by the 'sort' utility) before running it through 'diff' or 'join'. It doesn't have to be alphabetically -- it just matters that it's sorted in some sort of consistent order. I think, by default, 'sort' sorts in ASCII lexicographical order, which will be close enough to alphabetical (except capitals sort before lower-case letters). This, though, can be affected by your locale settings. -- Smiles, Les. -- Les Kitchen (LUV) ljk+luv at domain ljk.id.au via fastmail.fm _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
