Indicate "this" shell is shared

[meejah]

It would be good to have some way to indicate "this shell is being shared".

One method might be via already-provided tty-share environment variable (like TTY_SHARE) and the shell prompt. Or prompt-customiziation tools like Starship.

Alternatively, a "built in" method would be neat as well.

You can configure your prompt using the TTY_SHARE variables, like this:

export PS1='$([ -n "$TTY_SHARE_LOCAL_URL" ] && echo -n -e "\033[31;1;4mShWiM\033[0m 🐟 ")'$PS1
