 Another popular case is that in the AzureRM provider, there are a bunch of "association" resources, e.g. the `azurerm_network_interface_security_group_association`. These "association" resources represent the association relationship between two Terraform resources (in this case they are `azurerm_network_interface` and `azurerm_network_security_group`). They also have some synthetic resource ID, e.g. `/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/mygroup1/providers/microsoft.network/networkInterfaces/example|/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/group1/providers/Microsoft.Network/networkSecurityGroups/group1`.
 
 Currently, this tool only works on the assumption that there is 1:1 mapping between Azure resources and the Terraform resources.

+var reader = bufio.NewReader(os.Stdin)
+os.Setenv("AZTFY_DEBUG", "true")
+os.Setenv("AZTFY_MOCK_CLIENT", "false")
+os.Setenv("AZTFY_LOGFILE", "aztfylogs.log")
+
+log.Println("Main hitted")
+
+input, _ := reader.ReadString('\n')
+value := strings.TrimSpace(input)
+fmt.Printf("input: %v", value)
+```
+
+2. Run app
+```
+./aztfy rg-my-demo
+```
+
+1. Get pid of the app
+    - Linux : pgrep aztfy
+    - Windows : Task manager / tab detail
