As you say, Unix is an operating system (OS), and emacs is a program. So they are totally different.

Here's one way they are related. emacs (or vi) CANNOT run all by it's self. emacs depends on the OS. When you boot the computer, the OS always starts running first. Once the OS is running, emacs can run "on top of it".

You cannot boot up the computer to start running emacs first. The OS has to run first. The OS must be running first, in order that emacs can work.

Here's another way they are related. The OS is MUCH more complex than emacs. The OS takes care of all the background details, more than we can imagine.

Finally, when you boot the computer, there is normally one OS (linux, windows, etc.). And it just stays one OS. You can run countless programs, such as emacs or whatever. But the one OS keeps running the whole time.

"Commands" for emacs are like "delete this line", "copy this line", etc. "Commands" for the OS are like "cp file1 file2", "mkdir xxx", etc. They are totally different environments.

I hope this helps. The distinction between the OS and a program such as emacs is very important.

MODERATORS(5)							File Formats Manual						     MODERATORS(5)

NAME

       moderators - mail addresses for moderated Usenet newsgroups

DESCRIPTION

       The  GetModeratorAddress(3)  routine  reads  the file /etc/news/moderators to determine how to reach the moderator of a newsgroup.  This is
       used by inews(1) when an unapproved local posting is made to a moderated newsgroup.

       The file is read until a match is found.  Blank lines and lines starting with a number sign (``#'') are ignored.  All  other  lines  should
       consist of two fields separated by a colon.

       The  first  field  is  a  wildmat(3)-style pattern.  If it matches the name of the newsgroup, then the second field is taken to be a format
       string for sprintf(3).  This string should have at most one %s parameter, which will be given  the  name  of  the  newsgroup  with  periods
       transliterated to dashes.

       Here is a sample file:
	      foo.important:announce-request@foo.com
	      foo.*:%s@mailer.foo.com
	      gnu.*:%s@prep.ai.mit.edu
	      *:%s@uunet.uu.net
       Using the above file, postings to the moderated newsgroup in the left column will be sent to the address shown in the right column:
	      foo.important	  announce-request@foo.com
	      foo.x.announce	  foo-x-announce@mailer.foo.com
	      gnu.emacs.sources   gnu-emacs-sources@prep.ai.mit.edu
	      comp.sources.unix   comp-sources-unix@uunet.uu.net
