Lines 140-149... I have mixed feelings about that. On one hand, the software developer in me keeps screaming "DRY! DRY! DRY!". On the other hand I find it really concise and understandable. I mean, can you look at this code and NOT know what it does? Now try to make the code better - do you still get the same effect? Probably not. (disclaimer: I am arguing about this specific case, not about such code smells in general) UPDATE: ...and if I missed something besides that the code is repeated, please correct me. Bash is not my strong point.
