In PowerShell, you can use the Get-Variable cmdlet to get the variable names that are currently defined in the session. Simply run Get-Variable without any additional parameters to list all the variables along with their values. Additionally, you can use the Get-Member cmdlet to retrieve more information about the variables, such as their data type and scope. This can be helpful for debugging or when you need to access a specific variable by its name during script execution.
