Been looking at sed for the last two hours. Let me give a specific example of a few lines I would want to change: Let's say my original lines are: CN=DATA.OU=XYZ.O=CO CN=DATA.OU=XYY.OU=MEM.O=CO CN=DATA.OU=XZZ.OU=OOP.O=CO I want them to look like: CN=XYZ_DATA.OU=XYZ.O=CO CN=XYY_DATA.OU=XYY.OU=MEM.O=CO CN=XZZ_DATA.OU=XZZ.OU=OOP.O=CO So I need to take the data after the FIRST OU and stick in front of DATA with an _ in between. The rest of the line then remains the same. Hope it makes sense. Appreciate the help! Thanks, James
