I know that we can clear the entire buffer by using one of the following, as referenced here:

⌘ + K

printf '\33c\e[3J'

However, is it possible to clear the entire buffer except the last n lines?

  • Do not think it is possible in "right way" But you can detect window height/width and print spaces on all lines except last n lines. – Saboteur Oct 07 '21 at 23:31

You can clear the text on the current screen (up to the cursor position) using a different parameter (documented in XTerm Control Sequences):

printf '\033[1J'

Unlike \033[3J, this is a standard sequence which you may find in ECMA-48. Apple provides no relevant documentation.
