Method Execute

pocketbase.go:179–215

Execute initializes the application (if not already) and executes the pb.RootCmd with graceful shutdown support. This method differs from pb.Start() by not registering the default system commands!

// eagerParseFlags parses the global app flags before calling pb.RootCmd.Execute().
