macOS 允许在运行应用程序时向其传递特定参数，其中，-AppleLanguages 参数就是用来控制应用程序的语言的。
要知道一个应用都支持哪些界面语言，可以在 Finder 中找到该应用，点击右键选择显示包内容，然后查看 /Contents/Resources 目录下以 .lproj 结尾的语言文件目录；.lproj 之前的部分就是各语言对应的地区代码

# 以简体中文界面启动
open -a /System/Applications/Maps.app --args -AppleLanguages '(zh-CN)'

# 以英文界面启动
open -a /Applications/Safari.app --args -AppleLanguages '(en)'

open -na "Chrome" --args --incognito

BundleIdentifier

mdls -name kMDItemCFBundleIdentifier /Applications/Safari.app
# kMDItemCFBundleIdentifier = "com.apple.Safari"

osascript -e 'id of app "Finder" '
# com.apple.finder
