259 Usage: %s [OPTION-OR-FILENAME]...\n\
261 Run Emacs, the extensible, customizable, self-documenting real-time\n\
262 display editor. The recommended way to start Emacs for normal editing\n\
263 is with no options at all.\n\
265 Run M-x info RET m emacs RET m emacs invocation RET inside Emacs to\n\
266 read the main documentation for these command-line arguments.\n\
268 Initialization options:\n\
270 --batch do not do interactive display; implies -q\n\
271 --chdir DIR change to directory DIR\n\
272 --daemon start a server in the background\n\
273 --debug-init enable Emacs Lisp debugger for init file\n\
274 --display, -d DISPLAY use X server DISPLAY\n\
275 --no-desktop do not load a saved desktop\n\
276 --no-init-file, -q load neither ~/.emacs nor default.el\n\
277 --no-shared-memory, -nl do not use shared memory\n\
278 --no-site-file do not load site-start.el\n\
279 --no-splash do not display a splash screen on startup\n\
280 --no-window-system, -nw do not communicate with X, ignoring $DISPLAY\n\
281 --quick, -Q equivalent to -q --no-site-file --no-splash\n\
282 --script FILE run FILE as an Emacs Lisp script\n\
283 --terminal, -t DEVICE use DEVICE for terminal I/O\n\
284 --user, -u USER load ~USER/.emacs instead of your own\n\
290 FILE visit FILE using find-file\n\
291 +LINE go to line LINE in next FILE\n\
292 +LINE:COLUMN go to line LINE, column COLUMN, in next FILE\n\
293 --directory, -L DIR add DIR to variable load-path\n\
294 --eval EXPR evaluate Emacs Lisp expression EXPR\n\
295 --execute EXPR evaluate Emacs Lisp expression EXPR\n\
296 --file FILE visit FILE using find-file\n\
297 --find-file FILE visit FILE using find-file\n\
298 --funcall, -f FUNC call Emacs Lisp function FUNC with no arguments\n\
299 --insert FILE insert contents of FILE into current buffer\n\
300 --kill exit without asking for confirmation\n\
301 --load, -l FILE load Emacs Lisp FILE using the load function\n\
302 --visit FILE visit FILE using find-file\n\
308 --background-color, -bg COLOR window background color\n\
309 --basic-display, -D disable many display features;\n\
310 used for debugging Emacs\n\
311 --border-color, -bd COLOR main border color\n\
312 --border-width, -bw WIDTH width of main border\n\
313 --color, --color=MODE override color mode for character terminals;\n\
314 MODE defaults to `auto', and can also\n\
315 be `never', `auto', `always',\n\
316 or a mode name like `ansi8'\n\
317 --cursor-color, -cr COLOR color of the Emacs cursor indicating point\n\
318 --font, -fn FONT default font; must be fixed-width\n\
319 --foreground-color, -fg COLOR window foreground color\n\
320 --fullheight, -fh make the first frame high as the screen\n\
321 --fullscreen, -fs make first frame fullscreen\n\
322 --fullwidth, -fw make the first frame wide as the screen\n\
323 --maximized, -mm make the first frame maximized\n\
324 --geometry, -g GEOMETRY window geometry\n\
325 --no-bitmap-icon, -nbi do not use picture of gnu for Emacs icon\n\
326 --iconic start Emacs in iconified state\n\
327 --internal-border, -ib WIDTH width between text and main border\n\
328 --line-spacing, -lsp PIXELS additional space to put between lines\n\
329 --mouse-color, -ms COLOR mouse cursor color in Emacs window\n\
330 --name NAME title for initial Emacs frame\n\
331 --no-blinking-cursor, -nbc disable blinking cursor\n\
332 --reverse-video, -r, -rv switch foreground and background\n\
333 --title, -T TITLE title for initial Emacs frame\n\
334 --vertical-scroll-bars, -vb enable vertical scroll bars\n\
335 --xrm XRESOURCES set additional X resources\n\
336 --parent-id XID set parent window\n\
337 --help display this help and exit\n\
338 --version output version information and exit\n\
342 You can generally also specify long option names with a single -; for\n\
343 example, -batch as well as --batch. You can use any unambiguous\n\
344 abbreviation for a --option.\n\
346 Various environment variables and window system resources also affect\n\
347 Emacs' operation. See the main documentation.\n\
349 Report bugs to bug-gnu-emacs@gnu.org. First, please see the Bugs\n\
350 section of the Emacs manual or the file BUGS.\n"
