215 read the main documentation for these command-line arguments.\n\
217 Initialization options:\n\
221 --batch do not do interactive display; implies -q\n\
222 --chdir DIR change to directory DIR\n\
223 --daemon start a server in the background\n\
224 --debug-init enable Emacs Lisp debugger for init file\n\
225 --display, -d DISPLAY use X server DISPLAY\n\
228 --no-build-details do not add build details such as time stamps\n\
229 --no-desktop do not load a saved desktop\n\
230 --no-init-file, -q load neither ~/.emacs nor default.el\n\

242 --script FILE run FILE as an Emacs Lisp script\n\
243 --terminal, -t DEVICE use DEVICE for terminal I/O\n\
244 --user, -u USER load ~USER/.emacs instead of your own\n\
250 FILE visit FILE using find-file\n\
251 +LINE go to line LINE in next FILE\n\
252 +LINE:COLUMN go to line LINE, column COLUMN, in next FILE\n\
253 --directory, -L DIR prepend DIR to load-path (with :DIR, append DIR)\n\
254 --eval EXPR evaluate Emacs Lisp expression EXPR\n\
255 --execute EXPR evaluate Emacs Lisp expression EXPR\n\
258 --file FILE visit FILE using find-file\n\
259 --find-file FILE visit FILE using find-file\n\
260 --funcall, -f FUNC call Emacs Lisp function FUNC with no arguments\n\
261 --insert FILE insert contents of FILE into current buffer\n\
262 --kill exit without asking for confirmation\n\

277 --color, --color=MODE override color mode for character terminals;\n\
278 MODE defaults to `auto', and\n\
279 can also be `never', `always',\n\
280 or a mode name like `ansi8'\n\
281 --cursor-color, -cr COLOR color of the Emacs cursor indicating point\n\
282 --font, -fn FONT default font; must be fixed-width\n\

308 --version output version information and exit\n\
312 You can generally also specify long option names with a single -; for\n\
313 example, -batch as well as --batch. You can use any unambiguous\n\
314 abbreviation for a --option.\n\
316 Various environment variables and window system resources also affect\n\
317 the operation of Emacs. See the main documentation.\n\
