I think this is a good addition since I usually don't want the interactive one when setting up locally so it's really useful to have. However I think this should be combined with the existing CI environment variable (intended for use with things like github actions / jenkins) to skip the interactive parts.

Maybe initialize opt_skip based on if the CI environment variable is set and remove the -z $CI in the if statements where $opt_skip is used?

Also note that setting the CI environment variable should disable the tput colors so they shouldn't need to be removed.

Thanks for teaching me the CI environment variable @forslund. I've been using that here and I haven't had problems so far.
