I am creating a Script and I need to know what package manager each Popular Unix Distribution Uses (especially those distros that are commonly-used for Servers)...

I mean:
Debian uses apt-get
Fedora uses yum


Question: How to add blogger's RSS feed to facebook profile/page
Answer: You should forget about the user profile for that. First of all, you are not allowed to use the user profile for commercial reasons, it´s ONLY a user profile, for you and your friends, not a platform to advertise. And then there´s the problem with the Access Token. An Extended User Token lasts for 60 days, so you would have to refresh it every 2 months if you want to autopost stuff to Facebook.

Now for your Facebook Page, you can create an Extended Page Token that lasts forever. The rest is explained in the Facebook docs: https://developers.facebook.com/docs/graph-api/reference/v2.2/page/feed#publish

In general, you need to use a Page Token with publish_actions to post to the /page-id/feed endpoint.
