用户在Mac os平台上配置文件的时候有时候需要在Mac终端里面配置一些文件，这时候就需要用命令在终端里面打开app应用程序，但是有很多的用户不会使用终端命令，小编为大家提供了一个在终端下打开APP应用程序的教程。

打开终端 直接输入 open /Applications/xxx（应用的名称）.app 比如打开iTunes输入：open /Applications/iTunes.app （注意open之后需要空格再输入斜杠 / ）

Mac 下在终端中打开应用程序的命令

The command is simply open (which can also be used for opening directories). The most basic example of launching an application:

open /path/to/some.app

More complex possibilities also exist:

open "/Volumes/Macintosh HD/foo.txt"

opens the document in the default application for its type (as determined by LaunchServices).

open /Applications/

opens that directory in the Finder.

open -a /Applications/TextEdit.app "/Volumes/Macintosh HD/foo.txt"

opens the document in the application specified (in this case, TextEdit).

open -e "/Volumes/Macintosh HD/foo.txt"

opens the document in TextEdit (the -e option specifies TextEdit).

open http://www.apple.com/

opens the URL in the default browser (lynx, naturally *wink*)

open "file://localhost/Volumes/Macintosh HD/foo.txt"

opens the document in the default application for its type (as determined by LaunchServices).

open "file://localhost/Volumes/Macintosh HD/Applications/"

opens that directory in the Finder.
