Help in Emacs

[Rupam Jaiswal]

Hi,

I am using emacs. Many times, I have to open files just for viewing

and not

for editing.but by mistake some or the other lines get edited.

In order to avoid editing. Is there any way to open emacs in view mode

and not edit mode.(Just like in vi editior,where file can be open in

view mode by command view FileName).

Regards

Rupam

C-x C-r visits a file in read-only mode.

Or from the command line:

emacs --eval "(find-file-read-only \"Please Hammer Don't Hurt 'Em.txt\")"

You can also define a new command line option, like this:

;; Usage: emacs --read-only FILE

(defun command-line-find-file-read-only (switch)
(find-file-read-only (pop command-line-args-left)))

(add-to-list 'command-switch-alist
'("--read-only" . command-line-find-file-read-only))

There is the command `view-file' which will open a file read-only; in my
Emacs, it does not seem to be bound to any key, but you could bind it to
some convenient key in your .emacs.

Also, after opening a file, you can type C-x C-q (`toggle-read-only') to
put it in read-only mode. In the default mode line, this will also
result in two % characters in the left end of the mode line, indicating
that the file is read-only.
