trying to optimize find's searches ...
find works significantly faster when you bag various search patterns á la:
-iname '*.ko' -or -iname '*.bin' -or -iname '*.txt'
but, how could you do that using a batch strategy and setting a
variable with many "-[i]name ... -or -[i]name ..." cases?
line-by-line strategies are too slow
