If the loop will run only a few times it is ok but if the intended purpose is to run hundreds of times then it is better to find an alternative. Maybe you can try to replace the inner loop with something involving 'find ... -exec something' or some recursive grep and mix it with awk, I have found that it can be many times faster than using FOR loops.
