I need to know if there is a way of setting default file creation op[tions
dependent on what directory I am in. For example, if I am in /home/blah-blah,
a file I create will automatically be 664 and in group blah, while if I am in
/home/hum-dum and create a file it will be 644 and in group hum. I know how
to set default chmod options in general, but don't know how to make this
directory dependent and also toospecify a group upon creation.
