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 from:http://macosx.com/forums/howto-faqs/29520-how-launch-application-terminal.html 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:wxruiao.com 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.
