If you think this is true, use the existing mechanisms to test your
hypothesis.
PROMPT_COMMAND='cd $PWD || cd ${PWD%/*}'
will do much of what you say you want. You can modify that to fit your
needs: redirect stderr to /dev/null, use cd -P, make it into a shell
function that loops until cd succeeds, add something to print the new
current directory if the second cd succeeds, and so on.
