By default the function returns any objects with properties that are Equal (-eq) to the value of the parameter. To give you more flexibility you can modify the operator by using -NotEquals [ParameterName[]], -LessThan [ParameterName[]] and so on. Possible operators for all parameters are: -NotEquals -GreaterThan -GreaterThanOrEqual -LessThan -LessThanOrEquals Additional operators for [string] parameters are: -Like (supports * or % as wildcards) -NotLike -BeginsWith -EndsWith -Contains Properties with picklists are: Entities that have fields that refer to the base entity of this CmdLet: .INPUTS Nothing. This function only takes parameters. .OUTPUTS [Autotask.InventoryItem[]]. This function outputs the Autotask.InventoryItem that was returned by the API. .EXAMPLE Get-AtwsInventoryItem -Id 0 Returns the object with Id 0, if any. .EXAMPLE Get-AtwsInventoryItem -InventoryItemName SomeName Returns the object with InventoryItemName 'SomeName', if any. .EXAMPLE Get-AtwsInventoryItem -InventoryItemName 'Some Name' Returns the object with InventoryItemName 'Some Name', if any. .EXAMPLE Get-AtwsInventoryItem -InventoryItemName 'Some Name' -NotEquals InventoryItemName Returns any objects with a InventoryItemName that is NOT equal to 'Some Name', if any. .EXAMPLE Get-AtwsInventoryItem -InventoryItemName SomeName* -Like InventoryItemName Returns any object with a InventoryItemName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %. .EXAMPLE Get-AtwsInventoryItem -InventoryItemName SomeName* -NotLike InventoryItemName Returns any object with a InventoryItemName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %. .LINK New-AtwsInventoryItem .LINK Set-AtwsInventoryItem #> [CmdLetBinding(SupportsShouldProcess = $true, DefaultParameterSetName='Filter', ConfirmImpact='None')] Param ( #
