Could some kind soul give me a line like the following, but one that
includes 'auto-revert tail' and 'display-line'?

;;; -*- Mode: auto-revert -*-

Thanks,

Bob

Such requests for help should be posted to help-gnu-emacs <at> gnu.org, not
here.

To answer your question: it is better to use the file-local variables
section at the end of the file if you have more than one file-local
setting.  See the node "Specifying File Variables" in the Emacs user
manual for a detailed description.

The Emacs manual says (evaluate this sexp if you have the Info file
installed: (info "(emacs) Specifying File Variables")):

      Do not use the ‘mode’ keyword for minor modes.  To enable or disable
   a minor mode in a local variables list, use the ‘eval’ keyword with a
   Lisp expression that runs the mode command (*note Minor Modes::).  For
   example, the following local variables list enables ElDoc mode (*note
   Programming Language Doc::) by calling ‘eldoc-mode’ with no argument
   (calling it with an argument of 1 would do the same), and disables Font
   Lock mode (*note Font Lock::) by calling ‘font-lock-mode’ with an
   argument of −1.
   
        ;; Local Variables:
        ;; eval: (eldoc-mode)
        ;; eval: (font-lock-mode -1)
        ;; End:
   
   Note, however, that it is often a mistake to specify minor modes this
   way.  Minor modes represent individual user preferences, and it may be
   inappropriate to impose your preferences on another user who might edit
   the file.  If you wish to automatically enable or disable a minor mode
   in a situation-dependent way, it is often better to do it in a major
   mode hook (*note Hooks::).

So you could use this:

;; -*- eval: (auto-revert-mode); eval: (auto-revert-tail-mode); eval: (display-line-numbers-mode) -*-

[Message part 1 (text/plain, inline)]

Thanks for your very kind reply.

I will use help-gnu-emacs in the future for such pleas for help.

I do understand your suggestion to use the end of file stuff.  I use
it all the time.

However, in my one particular case I have a huge file
that is growing at the end and I love to watch it with 'tail' mode
and line numbers.

Thanks,

Bob

God bless you.

Just what I needed.

Thanks so much,
