find is a mini language for run over directories, and it is a must.
> xargs: Why?
if you have a directory with a very, very, very, very large number of files and
then you try a 'rm *' you will see why you need xargs. I use it a lot in
combination
with find. For example in the previous example a better way (faster):
find -type d -name xxxx -prune -o -type f -perm g=x | xargs chmod g-x
