Code:
sed 's/.*/A.& <> B.& or/; $s/ or$/;/'

Example:
Code:
$ cat data
AAA
BBB
CCC
DDD
EEE
FFF
GGG
HHH
$ sed 's/.*/A.& <> B.& or/; $s/ or$/;/' data
A.AAA <> B.AAA or
A.BBB <> B.BBB or
A.CCC <> B.CCC or
A.DDD <> B.DDD or
A.EEE <> B.EEE or
A.FFF <> B.FFF or
A.GGG <> B.GGG or
A.HHH <> B.HHH;

BBB
CCC
DDD
EEE

======================

"test.txt" 7L, 25C written

A.AAA <> B.AAA or
A.BBB <> B.BBB or
A.CCC <> B.CCC or
A.DDD <> B.DDD or
A.EEE <> B.EEE or

A.BBB <> B.BBB or
A.CCC <> B.CCC or
A.DDD <> B.DDD or
A.EEE <> B.EEE or
A.FFF <> B.FFF ;

Take a look at your data file with `od` or `hexdump` or `vis` or `sed -n l` or `cat -vet` and you'll probably find some character that doesn't show up on your terminal; that's almost certainly the source of the extra line at the end of my sed suggestion's output. Perhaps it's a stray carriage return or other control character?

Also, your sample output in your most recent post differs from that of your original post. The latter has a space before the final semi-colon; the former does not. If you want that space, use this slightly modified version of my original suggestion:
Code:
sed 's/.*/A.& <> B.& or/; $s/or$/;/'

Alister
