You’re working on a Dell machine remotely and need to know the service tag or chassis type.
You can easily get that from WMI with `wmic`:
> wmic systemenclosure get ‘SerialNumber,ChassisTypes’ /value
The “ChasisTypes” is included because Dell has a habit of having several different form factors for some models and the service tag isn’t enough to differentiate which model you’re working with. The different values for the chassis type are documented in the Windows Management Instrumentation online reference. In this example, it is a “lunchbox” chassis; what Dell would call an “Ultra Small Form Factor”.
