29 ;; one in the list below; first described means first handled. Options
30 ;; within each category (delimited by a bar) are handled in the order
31 ;; encountered on the command line.
33 ;; -------------------------
34 ;; -version Print Emacs version to stderr, then exit
35 ;; --version successfully right away.
36 ;; This option is handled by emacs.c
37 ;; -------------------------
38 ;; -help Print a short usage description and exit
39 ;; --help successfully right away.
40 ;; This option is handled by emacs.c
41 ;; -------------------------
42 ;; -nl Do not use shared memory (for systems that
43 ;; -no-shared-memory support this) for the dumped Emacs data.
44 ;; This option is handled by emacs.c
47 ;; --map-data This option is handled by emacs.c
48 ;; -------------------------
49 ;; -t FILE Use FILE as the name of the terminal.
50 ;; --terminal FILE Using this implies "-nw" also.
51 ;; This option is handled by emacs.c
52 ;; -------------------------
53 ;; -d DISPNAME Use DISPNAME as the name of the X-windows
54 ;; -display DISPNAME display for the initial frame.
55 ;; --display DISPNAME This option is handled by emacs.c
56 ;; -------------------------
57 ;; -nw Do not use a windows system (but use the
58 ;; --no-windows terminal instead.)
59 ;; This option is handled by emacs.c
60 ;; -------------------------
61 ;; -batch Execute noninteractively (messages go to stdout,
62 ;; --batch variable noninteractive set to t)
63 ;; This option is handled by emacs.c
64 ;; -------------------------
65 ;; -q Do not load user's init file and do not load
66 ;; -no-init-file "default.el". Regardless of this switch,
67 ;; --no-init-file "site-start" is still loaded.
68 ;; -------------------------
69 ;; -no-site-file Do not load "site-start.el". (This is the ONLY
70 ;; --no-site-file way to prevent loading that file.)
71 ;; -------------------------
72 ;; -u USER Load USER's init file instead of the init
73 ;; -user USER file belonging to the user starting Emacs.
75 ;; -------------------------
76 ;; -debug-init Don't catch errors in init files; let the
77 ;; --debug-init debugger run.
78 ;; -------------------------
79 ;; -i ICONTYPE Set type of icon using when Emacs is
80 ;; -itype ICONTYPE iconified under X-windows.
81 ;; --icon-type ICONTYPE This option is passed on to term/x-win.el
83 ;; -iconic Start Emacs iconified under X-windows.
84 ;; --iconic This option is passed on to term/x-win.el
85 ;; -------------------------
86 ;; Various X-windows options for colors/fonts/geometry/title etc.
87 ;; These options are passed on to term/x-win.el which see. Certain
88 ;; of these are also found in term/pc-win.el
89 ;; -------------------------
92 ;; -L DIRNAME Add DIRNAME to load-path
94 ;; --directory DIRNAME
96 ;; -l FILE Load and execute the Emacs lisp code
97 ;; -load FILE in FILE.
100 ;; -f FUNC Execute Emacs lisp function FUNC with
101 ;; -funcall FUNC no arguments. The "-e" form is outdated
102 ;; --funcall FUNC and should not be used. (It's a typo
103 ;; -e FUNC promoted to a feature.)
105 ;; -eval FORM Execute Emacs lisp form FORM.
108 ;; -insert FILE Insert the contents of FILE into buffer.
110 ;; -------------------------
111 ;; -kill Kill (exit) Emacs right away.
