Unix Tip #4534- August 10, 2018

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!


NOTE: All tips provided are USE AT YOUR OWN RISK. Tips are submitted by various unix admins around the globe. UGU suggest you read and test each tip in a non-volitile environment before placing into production.
