Thank you for sharing that page with me. Maybe, little-by-little, I might be starting to learn something. The tone and authority with which the writer(s) pontificated, was, for noobie-me, like sitting at the feet of Gamalial:
" . . . On a more esoteric level, sudo provides some features which encourage different work habits, which can positively impact the security of the system. sudo is commonly used to execute only a single command, while su is generally used to open a shell and execute multiple commands. The sudo approach reduces the likelihood of a root shell being left open indefinitely, and encourages the user to minimize their use of root privileges . . .."
Often, at my computer, I marvel over what must have been the impact of then-Bishop Desmond TuTu's Ubuntu theology as the basis of his anti-apartheid work and 1984 Nobel Peace Prize on a then-11-year old, privileged Afrikaner boy (Mark Shuttleworth)?
P.S. I'll leave my Mint and Ubuntu as is.
