Where does “open -b bundle_indentifier” get path to program from?

问题

For example i run in console "open -b com.apple.dt.Xcode", how does open determine what program to launch?

回答1:

If you want path to program, you can use applescript.

  osascript -e "POSIX path of (path to application id \"com.apple.dt.Xcode\")"

回答2:

Bundle identifiers are generally declared in an applications's app bundle Info.plist. The values are identified and registered by various means in OS X and managed in the Launch Services database. Read the Launch Services Programming Guide for detailed information, in particular, the section on Application Registration.
