Good day all,
I am trying to write a little script that in certain situations lets
emacs show a file containing a scrollback-buffer. I am using emacs
with multi-tty support ("emacs --version" yields "GNU Emacs
23.0.60.1"). There's a daemon running ("emacs --daemon"), so I thought
it might be quick enough to view the scrollback buffer with
"emacsclient -t <file>". I am experimenting with gnu-screen,
http://www.gnu.org/software/screen/ , and would like to use
"emacsclient -t" to view, and get keyboard access to, the scrollback
buffer (with emacs-style cursor navigation, copy/paste etc).
The buffer is written to a file, /tmp/screenscrollbackbuffer. I'd like
to do the following:
(A) make emacs show the file in read-only mode.
(B) have the cursor automatically moved to the end of the file at start-up.
(C) possibly have emacs starting with auto-revert-tail-mode or
auto-revert-mode enabled as well..
How do I do this? Can I configure this stuff on the command line? How?
Or should I write an .emacs-style configuration file that this scripts
somehow passes to emacsclient?
Best regards

You can do it on the command line. See the [Appendix C Command Line
Arguments for] Emacs Invocation node in the Emacs manual.
