I had a think about this (as I'm doing the same thing), and I realized that in terms of efficiency, it's not a big difference. UNLESS you're cutting data on each sed call to reduce the number of steps. If you loop over n lines 50 times, and perform 2 sed operations, that's 100 steps. If you loop over n lines 50 times for one operation, and do it again for a second operation, that's still 100 steps. In both cases, the big O complexity is O(n). If I've misunderstood, please correct me! As I understand, we won't be tested on efficiency this way anyway (Michael said we'll just be tested on how fast our program runs).
