Move-Item [-Path] [[-Destination] ] [-Force] [-Filter ] [-Include ] [-Exclude ] [-PassThru] [-Credential ] [-WhatIf] [-Confirm] [-UseTransaction] []
If my understanding is correct, that only parameters which are completely enclosed in brackets are optional, then the only mandatory parameter is -Path(not enclosed in brackets). If you only use the -Path parameter you get an error. This is a general question about help, not the move-item command.
