I think (IANA bash expert) PS1 should be a pretty good indicator,
unless something funny is going on :)
(Note the difference between executing and sourcing):
(IDK if other shells use PS1 so it would work in such environments)
I looked in man ps to see if possibly ps -o <something> could make
an easy check (seems like there ought to be, but I am out of time
after almost an hour of experimenting :/ )
--8<---------------cut here---------------start------------->8---
[13:23 ~/bs]$ guile --no-auto-compile -c '(display (getenv "PS1"))(newline)'
[\A \w]\$
[13:24 ~/bs]$ ./guile-non-int-call
PS1_val='#f'
#f
[13:24 ~/bs]$ source ./guile-non-int-call
PS1_val='[\A \w]\$ '
[\A \w]\$
[13:24 ~/bs]$ cat -nA ./guile-non-int-call

2 PS1_val="$(guile --no-auto-compile -c '(display (getenv

3 echo "PS1_val='$PS1_val'"$
4 guile --no-auto-compile -c '(display (getenv "PS1"))(newline)'$
