Hi, >>How would I write I want to find 'CP_', but NOT instances of 'CPLAT::CP_'? >What comes before 'CP_' when you want a match? Whitespace, other chars, is it >just 'CPLAT::CP_' you don't want? Yes whitespace always. So what I am doing is a massive replace. So this grep will allow me to see how many instances still need to be replaced. I am replacing CP_ with CPLAT::CP_ and when i execute the grep I want to ignore CPLAT:CP_ so I just see the CP_ that still need to be done. -Jason
