You could also try this logic which builds a temp file for fileB without the last two fields and then just uses grep -f, however if fileB is large, then the script may a little lacking in performance. I've used the internal code rather than some convoluted echo $line through some sort of field counter, subtract two then echo $line | cut -f -$wanted that spawns several processes for each record trim and is a lot slower, but I've seen it quite a lot elsewhere and probably used it myself too before I found a better way :-
Code:
#!/bin/ksh
{ cat fileB | while read line
do
outline="${line% * *}"
echo $outline
done } > temp-fileB
grep -f temp-fileB fileA > fileC
grep -vf temp-fileB fileA > fileD
Does this help?
