Hello everyone

Im sure this has been asked lots of times before, but after endless searching i cant find what i need.
How can i make a bash script unreadable to all, including root, but still executable, im not worried about editing it again etc... , is there a way to convert it or something, i have tried chmod and chown, but root is still able to view the script, or is not possible.
Thanks in advance for any help.

Dave
