Say that you have a cron job on each one of your Linux systems, and you have a script to collect the hardware information from each: #!/bin/bash Create Simulatorsįirst, let's see how you would create a new simulator.In this article, I present a few tricks to handle error conditions-Some strictly don't fall under the category of error handling (a reactive way to handle the unexpected) but also some techniques to avoid errors before they happen.Ĭase study: Simple script that downloads a hardware report from multiple hosts and inserts it into a database. With these UUIDs, you will be able to interact with those simulators. IPhone 11 Pro (83A0E104-F321-493A-AB1F-60EFF4AB7219 ) (Shutdown )Īs you can see, each device will have a unique identifier and its state, Shutdown or Booted. IPhone 11 (C56AFC2D-7BE5-447C-B4AA-ED8940498164 ) (Shutdown ) Normally, grub-mkconfig will generate menu entries that use universally-unique identifiers (UUIDs) to identify the root filesystem to the Linux kernel. Otherwise, it will chose a time-based UUID. IPhone 8 Plus (1B71B733-922D-4E3F-8218-35B0214E0088 ) (Shutdown ) By default uuidgen will generate a random-based UUID if a high-quality random number generator is present. To make the procedure confined and comprehensive in terms of understanding functionality, here we are depicting an analytical overview of the bash UUID. If you need a unique ID in a script, you can create a GUID, as needed. WatchOS 6.2 ( 6.2 - 17T256 ) - .watchOS-6-2 The New-Guid cmdlet creates a random globally unique identifier (GUID). ) (unavailable, The iOS 9.3 simulator runtime is not supported on hosts after macOS 10.14.99.
