Entering and Exiting Emacs
The usual way to invoke Emacs is to type `emacs RET' at the shell.
To invoke Lucid Emacs, type `lemacs RET'. Emacs clears the screen and
then displays an initial advisory message and copyright notice. You
can begin typing Emacs commands immediately afterward.
Some operating systems insist on discarding all type-ahead when Emacs
starts up; they give Emacs no way to prevent this. Therefore, it is
wise to wait until Emacs clears the screen before typing the first
Before Emacs reads the first command, you have not had a chance to
give a command to specify a file to edit. Since Emacs must always have
a current buffer for editing, it presents a buffer, by default, a
buffer named `*scratch*'. The buffer is in Lisp Interaction mode; you
can use it to type Lisp expressions and evaluate them, or you can
ignore that capability and simply doodle. You can specify a different
major mode for this buffer by setting the variable `initial-major-mode'
in your init file. Note: Init File.
It is possible to give Emacs arguments in the shell command line to
specify files to visit, Lisp files to load, and functions to call.
