What Cmdlet can show us the properties and methods of an object?

The Cmdlet that can show us the properties and methods of an object in PowerShell is Get-Member.

Here are the steps to use it:

1. Open PowerShell.
2. Create or get the object you want to inspect. For example, if you want to inspect a string object, you can create one like this: $myString = "Hello, World!".
3. Use the Get-Member cmdlet to inspect the object. Following the previous example, you would type: $myString | Get-Member.
4. Press Enter. PowerShell will display a list of all the methods and properties of the object.

Remember that you need to use the pipe operator (|) to pass the object to the Get-Member cmdlet.
