I have used Linux for most my life, and it hat been my daily driver for nearly two decades now. I have been bugged recently how when I exit the terminal buffer has not been cleared leaving whatever contents available to the next user to view.

a quick man zsh I found the STARTUP/SHUTDOWN FILES, and then a quick search on resetting the termianl buffer led me to <esc>c or printf "\033c".

In five minutes something which has bothered me for who knows how long was resolved. Just needed some motivation to figure it out.
