176 Usage: %s [OPTION-OR-FILENAME]...\n\
178 Run Emacs, the extensible, customizable, self-documenting real-time\n\
179 display editor. The recommended way to start Emacs for normal editing\n\
180 is with no options at all.\n\
182 Run M-x info RET m emacs RET m emacs invocation RET inside Emacs to\n\
183 read the main documentation for these command-line arguments.\n\
185 Initialization options:\n\
187 --batch do not do interactive display; implies -q\n\
188 --chdir DIR change to directory DIR\n\
189 --daemon start a server in the background\n\
190 --debug-init enable Emacs Lisp debugger for init file\n\
191 --display, -d DISPLAY use X server DISPLAY\n\
192 --no-desktop do not load a saved desktop\n\
193 --no-init-file, -q load neither ~/.emacs nor default.el\n\
194 --no-shared-memory, -nl do not use shared memory\n\
195 --no-site-file do not load site-start.el\n\
196 --no-site-lisp, -nsl do not add site-lisp directories to load-path\n\
197 --no-splash do not display a splash screen on startup\n\
198 --no-window-system, -nw do not communicate with X, ignoring $DISPLAY\n\
199 --quick, -Q equivalent to:\n\
200 -q --no-site-file --no-site-lisp --no-splash\n\
201 --script FILE run FILE as an Emacs Lisp script\n\
202 --terminal, -t DEVICE use DEVICE for terminal I/O\n\
203 --user, -u USER load ~USER/.emacs instead of your own\n\
209 FILE visit FILE using find-file\n\
210 +LINE go to line LINE in next FILE\n\
211 +LINE:COLUMN go to line LINE, column COLUMN, in next FILE\n\
212 --directory, -L DIR add DIR to variable load-path\n\
213 --eval EXPR evaluate Emacs Lisp expression EXPR\n\
214 --execute EXPR evaluate Emacs Lisp expression EXPR\n\
215 --file FILE visit FILE using find-file\n\
216 --find-file FILE visit FILE using find-file\n\
217 --funcall, -f FUNC call Emacs Lisp function FUNC with no arguments\n\
218 --insert FILE insert contents of FILE into current buffer\n\
219 --kill exit without asking for confirmation\n\
220 --load, -l FILE load Emacs Lisp FILE using the load function\n\
221 --visit FILE visit FILE using find-file\n\
227 --background-color, -bg COLOR window background color\n\
228 --basic-display, -D disable many display features;\n\
229 used for debugging Emacs\n\
230 --border-color, -bd COLOR main border color\n\
231 --border-width, -bw WIDTH width of main border\n\
232 --color, --color=MODE override color mode for character terminals;\n\
233 MODE defaults to `auto', and\n\
234 can also be `never', `always',\n\
235 or a mode name like `ansi8'\n\
236 --cursor-color, -cr COLOR color of the Emacs cursor indicating point\n\
237 --font, -fn FONT default font; must be fixed-width\n\
238 --foreground-color, -fg COLOR window foreground color\n\
239 --fullheight, -fh make the first frame high as the screen\n\
240 --fullscreen, -fs make the first frame fullscreen\n\
241 --fullwidth, -fw make the first frame wide as the screen\n\
242 --maximized, -mm make the first frame maximized\n\
243 --geometry, -g GEOMETRY window geometry\n\
244 --no-bitmap-icon, -nbi do not use picture of gnu for Emacs icon\n\
245 --iconic start Emacs in iconified state\n\
246 --internal-border, -ib WIDTH width between text and main border\n\
247 --line-spacing, -lsp PIXELS additional space to put between lines\n\
248 --mouse-color, -ms COLOR mouse cursor color in Emacs window\n\
249 --name NAME title for initial Emacs frame\n\
250 --no-blinking-cursor, -nbc disable blinking cursor\n\
251 --reverse-video, -r, -rv switch foreground and background\n\
252 --title, -T TITLE title for initial Emacs frame\n\
253 --vertical-scroll-bars, -vb enable vertical scroll bars\n\
254 --xrm XRESOURCES set additional X resources\n\
255 --parent-id XID set parent window\n\
256 --help display this help and exit\n\
257 --version output version information and exit\n\
261 You can generally also specify long option names with a single -; for\n\
262 example, -batch as well as --batch. You can use any unambiguous\n\
263 abbreviation for a --option.\n\
265 Various environment variables and window system resources also affect\n\
266 Emacs' operation. See the main documentation.\n\
