Before you do this, make sure you understand the reasoning
for setting it to 0022 in RH/fedora which is that by creating
a group for every user, you do not automatically have any
additional privileges permitted.  That is, there are no
members but yourself in your default group.  Now, if you ever
want to permit shared access somewhere, all you have to do is
create groups with appropriate members or add members to your
own group.  If you did not already have group access arranged
it is much more difficult to add it later.

Now if you still want to make the change, it is set for most
things in /etc/bashrc.
