It is actually quite easy, just run it from terminal like this:
它实际上很简单，只需像这样从终端运行它：
/Applications/Emacs.app/Contents/MacOS/Emacs -nw
the -nw option means to start emacs without the gui frame.
-nw 选项意味着在没有 gui 框架的情况下启动 emacs。
You can put the following in your shell (on my mac .zshenv) :
您可以将以下内容放入您的 shell（在我的 mac .zshenv 上）：
alias Emacs="/Applications/Emacs.app/Contents/MacOS/Emacs -nw"
Then I just have two commands:
然后我只有两个命令：
Emacs: for emacs version 24
Emacs: 对于 emacs 版本 24
emacs: for the apple version of emacs
emacs: 苹果版的emacs
Of course you can just alias the Emacs.app to emacs, but this allows me to customize the two differently - for instance Emacs 24 allows me to use list-packages and so forth. emacs 22 ignores most of this, so I can always revert to a 'bare metal' emacs if need be. Your usage may vary, but if you don't remember the arguments to emacs you can find them by doing this:
当然，您可以将 Emacs.app 别名为 emacs，但这允许我以不同的方式自定义两者 - 例如 Emacs 24 允许我使用列表包等等。emacs 22 忽略了大部分内容，因此如果需要，我总是可以恢复到“裸机”emacs。您的用法可能会有所不同，但如果您不记得 emacs 的参数，您可以通过执行以下操作找到它们：
emacs --help
Some interesting ones:
一些有趣的：
Emacs.app --fullscreen
Emacs.app --line-spacing
Emacs.app --vertical-scroll-bars

The answer from @Toymakerii is a good one, but you might also consider adding:
@Toymakerii 的回答很好，但您也可以考虑添加：
export PATH=/Applications/Emacs.app/Contents/MacOS/bin:$PATH
This way, you can use emacsclientto open files in an already-running Emacs instance:
这样，您可以使用emacsclient在已经运行的 Emacs 实例中打开文件：
emacsclient -t SOMEFILE # Open SOMEFILE in a terminal frame
emacsclient -c SOMEFILE # Open SOMEFILE in a new graphical frame
Depending on your Emacs version, you might need to put the following in your ~/.emacs.d/init.el(or ~/.emacs, if you're old-fashioned):
根据您的 Emacs 版本，您可能需要将以下内容放入~/.emacs.d/init.el（或者~/.emacs，如果您是老式的）：
(require 'server)
(unless (server-running-p)
(server-start))

In my ~/.profilei have the following:
在我的~/.profile我有以下内容：
function emacs
{
if [ -e "$@" ]
then
command open -a emacs "${@}"
else
touch "$@"
command open -a emacs "${@}"
fi
}
(The reason for having a function is to make it also work when the specified file does not yet exist when emacs is started)
（之所以有功能，是为了在emacs启动时指定文件还不存在的情况下，让它也能工作）

The easiest is to simply do
最简单的就是简单地做
open /Applications/Emacs.app --args foo
An alias would then be
一个别名将是
alias emacs=open /Applications/Emacs.app --args "${@}"
or in csh/tcsh
或在 csh/tcsh
alias emacs 'open /Applications/Emacs.app --args '
edit: this seems to need a full path to open the correct file... I don't know if this is a problem with Emacs.app or with tcsh
编辑：这似乎需要一个完整的路径来打开正确的文件......我不知道这是 Emacs.app 还是 tcsh 的问题

By default terminal will open /usr/bin/emacs on OS X. You can change this behavior by changing what the "emacs" command will do. Open up ~/.profile and type the following:
默认情况下，终端将在 OS X 上打开 /usr/bin/emacs。您可以通过更改“emacs”命令将执行的操作来更改此行为。打开 ~/.profile 并输入以下内容：
alias emacs=open /Applications/Emacs.app
The next time you open a prompt this change will be active. (or you can run "source ~/.profile")
下次打开提示时，此更改将处于活动状态。（或者你可以运行“source ~/.profile”）
