PROTECT THE ROOT DIRECTORY AT ALL COST

Here is a little extra guard that can be taken if
anyone attempts, or accidentally recursively removes
files inside a directory. If and when it occurs,
the person will constantly be prompted with the
question"are you sure?"

Here is how it works in a safe area:

% cd /usr/tmp
% mkdir foo
% touch /usr/tmp/foo/\-i
% chmod 000 /usr/tmp/foo/\-i

NOTE: Use the fully qualified path to create the
file when creating.

% cd foo
% touch fee fii foo fum
% rm -rf *


Every little bit helps!
