I'm new with Emacs and come from Joe.

There I started editing mail from the command line by

joe -rmargin 60

because I don't want to generally set the right margin to 60.

I can't find a similar command-line option in Emacs.

Is there one somewhere?

    What do you mean by "line wrap"? Are you talking about having the editor break up lines at a given column, or are you talking about how it displays text you're editing? – DoMiNeLa10 Jul 18 at 16:05
  • Hi, I want to have the file saved after editing broken up lines at column 60. I'm not interested in how the file is displayed. – tmp1 Jul 20 at 8:00
  • You could try setting the variable per-buffer for your mode for editing emails, or for text-mode, so that filling is set only for editing text rather than code. If you want to have that specific setting for a given instance of Emacs, you might want to look into the --eval option. – DoMiNeLa10 Jul 22 at 15:02

While emacs doesn't have this feature, you can evaluate elisp on startup:

emacs --eval "(setq fill-column 60)"

With emacs 27 you can draw this on startup too:

emacs --eval "(progn (setq fill-column 60) (display-fill-column-indicator-mode))"
  • My Emacs is 26.1 emacs --eval "(setq fill-column 60)" does not what is promised - I suppose I have to load some "elisp" feature? But in the first place I'm content to learn that there is no such option and I have to look for workarounds. – tmp1 Jul 24 at 11:28
