Linux is a UNIX Clone But if you consider Portable Operating System Interface (POSIX) standards then Linux can be considered as UNIX.

Linux Manual Pages -- The Linux Documentation Project Works The Linux Documentation Project maintains an archive of snaphots of the (English language) core Linux manual pages that are maintained by Michael Kerrisk. Corrections and additions are welcome, but review the "Help Wanted" list, first. Man pages belonging to programs are usually distributed together with those programs. The latest version is man-pages-3.55.tar.gz (1.8Mb) (TLDP mirror), or man-pages-3.55.tar.bz2 (1.2Mb) (TLDP mirror). Man pages are authored using the traditional troff typesetting format, which dates back to the early days of UNIX. A tarball containing an HTML-based compilation consisting of core man-pages, and several other sources, can be downloaded from the man-html directory. Other useful search and/or indexed compilations of man pages can be found at:
Change Your Life | Are You Living or Surviving? troff.org -- the Text Processor for Typesetters Improve Your Relationship By Taking Care of Yourself First By Nancy J. Wasson, Ph.D. It’s important for you to take care of yourself before you try to fix your relationship. The old saying ‘You can’t give away what you don’t have” applies here. Until you are peaceful and happy, you won’t have a peaceful, happy relationship. If you skip these steps and jump immediately into the murky waters of your troubled relationship, you are at high risk for going under. Before you confront core relationship issues, first follow these two steps to increase your chances of success: 1. Make yourself a promise that you’re going to take good care of yourself and be okay no matter what happens in your relationship. One reason is that you will be perceived as emotionally needy and dependent. Another reason is that it’s too heavy of a burden to feel totally responsible for another person’s happiness. By showing respect for yourself and belief in your ability to thrive whether in a relationship or not, you’ll be coming from a place of empowerment and strength.
