30 ;; one in the list below; first described means first handled. Options
31 ;; within each category (delimited by a bar) are handled in the order
32 ;; encountered on the command line.
34 ;; -------------------------
35 ;; -version Print Emacs version to stderr, then exit
36 ;; --version successfully right away.
37 ;; This option is handled by emacs.c
38 ;; -------------------------
39 ;; -help Print a short usage description and exit
40 ;; --help successfully right away.
41 ;; This option is handled by emacs.c
42 ;; -------------------------
43 ;; -nl Do not use shared memory (for systems that
44 ;; -no-shared-memory support this) for the dumped Emacs data.
45 ;; This option is handled by emacs.c
48 ;; --map-data This option is handled by emacs.c
49 ;; -------------------------
50 ;; -t FILE Use FILE as the name of the terminal.
51 ;; --terminal FILE Using this implies "-nw" also.
52 ;; This option is handled by emacs.c
53 ;; -------------------------
54 ;; -d DISPNAME Use DISPNAME as the name of the X
55 ;; -display DISPNAME display for the initial frame.
56 ;; --display DISPNAME This option is handled by emacs.c
57 ;; -------------------------
58 ;; -nw Do not use a windows system (but use the
59 ;; --no-windows terminal instead.)
60 ;; This option is handled by emacs.c
61 ;; -------------------------
62 ;; -batch Execute noninteractively (messages go to stdout,
63 ;; --batch variable noninteractive set to t)
64 ;; This option is handled by emacs.c
65 ;; -------------------------
66 ;; -q Do not load user's init file and do not load
67 ;; -no-init-file "default.el". Regardless of this switch,
68 ;; --no-init-file "site-start" is still loaded.
69 ;; -------------------------
70 ;; -no-site-file Do not load "site-start.el". (This is the ONLY
71 ;; --no-site-file way to prevent loading that file.)
72 ;; -------------------------
73 ;; -u USER Load USER's init file instead of the init
74 ;; -user USER file belonging to the user starting Emacs.
76 ;; -------------------------
77 ;; -debug-init Don't catch errors in init files; let the
78 ;; --debug-init debugger run.
79 ;; -------------------------
80 ;; -i ICONTYPE Set type of icon using when Emacs is
81 ;; -itype ICONTYPE iconified under X.
82 ;; --icon-type ICONTYPE This option is passed on to term/x-win.el
84 ;; -iconic Start Emacs iconified.
85 ;; --iconic This option is passed on to term/x-win.el
86 ;; -------------------------
87 ;; Various X options for colors/fonts/geometry/title etc.
88 ;; These options are passed on to term/x-win.el which see. Certain
89 ;; of these are also found in term/pc-win.el
90 ;; -------------------------
97 ;; -L DIRNAME Add DIRNAME to load-path
99 ;; --directory DIRNAME
101 ;; -l FILE Load and execute the Emacs lisp code
102 ;; -load FILE in FILE.
105 ;; -f FUNC Execute Emacs lisp function FUNC with
106 ;; -funcall FUNC no arguments. The "-e" form is outdated
107 ;; --funcall FUNC and should not be used. (It's a typo
108 ;; -e FUNC promoted to a feature.)
110 ;; -eval FORM Execute Emacs lisp form FORM.
115 ;; -insert FILE Insert the contents of FILE into buffer.
117 ;; -------------------------
118 ;; -kill Kill (exit) Emacs right away.
