Application Control and Status¶
The functioning system is comprised of applications. Each application has a name and a version number. An application may have multiple processes running within and each process has its own state.
Application Status¶
The command app status is used to display the status of the system. When the command is executed, it requests an up-to-date status of every application and process, and hence may take a few seconds to return.
A typical app status screen from the command line interface:
