If you can use tmux or screen, they have the ability to save the scrollback buffer to a file.

Write all tmux scrollback to a file

Copying GNU screen scrollback buffer to file (extended hardcopy)?

Unlike screendump, which is Linux-only, tmux and screen are available for BSD-based OSes too (e.g. macOS, FreeBSD) and won't require special permissions.

Because of that, I marked this one as accepted. But @RudiC Don't take it personally. Your solution is still the simplest.

Those two add another layer; you need to login and then run screen, have another shell, and then can communicate with your CLI.
