You could try with the expression similar to this:-

Code:

grep "^[0-9]*,[0-9]*, ,009[19] inputfile

I think that this translates as:-
Does that get you started? You may need to use grep -E or egrep with the character | as a logical or between them if you want to have multiple options, e.g.:-

Code:

grep -E "^[0-9]*,[0-9]*, ,009[19]|^[0-9]*,[0-9]*, ,9[19]|^[0-9]*,[0-9]*, ,[0-9]*,009[19]|^[0-9]*,[0-9]*, ,[0-9]*,9[19] inputfile

I hope that this helps. I might have missed the point, so please show me some more input & expected results along with what you have tried & the output and I will see if we can refine it a bit.
