To give me sudo access to a Ubuntu server.
Run:
sudo ./create_rda_user_with_sudo_access.sh
One liner:
cd /tmp && git clone https://github.com/rorydavidson/ssh_access.git && cd ssh_access && ./create_rda_user_with_sudo_access.sh && echo 'Rory has access' && cd .. && rm -r ssh_access
Thanks to @mattwillsher for the idea & @kaicode for nudging me to do it!
