Activity Parameters

The following table lists the recommended names and functionality for activity parameters.

Parameter	Functionality
Append Data type: SwitchParameter	Implement this parameter so that the user can add content to the end of a resource when the parameter is specified.
CaseSensitive Data type: SwitchParameter	Implement this parameter so the user can require case sensitivity when the parameter is specified.
Command Data type: String	Implement this parameter so the user can specify a command string to run.
CompatibleVersion Data type: System.Version object	Implement this parameter so the user can specify the semantics that the cmdlet must be compatible with for compatibility with previous versions.
Compress Data type: SwitchParameter	Implement this parameter so that data compression is used when the parameter is specified.
Compress Data type: Keyword	Implement this parameter so that the user can specify the algorithm to use for data compression.
Continuous Data type: SwitchParameter	Implement this parameter so that data is processed until the user terminates the cmdlet when the parameter is specified. If the parameter is not specified, the cmdlet processes a predefined amount of data and then terminates the operation.
Create Data type: SwitchParameter	Implement this parameter to indicate that a resource is created if one does not already exist when the parameter is specified.
Delete Data type: SwitchParameter	Implement this parameter so that resources are deleted when the cmdlet has completed its operation when the parameter is specified.
Drain Data type: SwitchParameter	Implement this parameter to indicate that outstanding work items are processed before the cmdlet processes new data when the parameter is specified. If the parameter is not specified, the work items are processed immediately.
Erase Data type: Int32	Implement this parameter so that the user can specify the number of times a resource is erased before it is deleted.
ErrorLevel Data type: Int32	Implement this parameter so that the user can specify the level of errors to report.
Exclude Data type: String[]	Implement this parameter so that the user can exclude something from an activity. For more information about how to use input filters, see Input Filter Parameters.
Filter Data type: Keyword	Implement this parameter so that the user can specify a filter that selects the resources upon which to perform the cmdlet action. For more information about how to use input filters, see Input Filter Parameters.
Follow Data type: SwitchParameter	Implement this parameter so that progress is tracked when the parameter is specified.
Force Data type: SwitchParameter	Implement this parameter to indicate that the user can perform an action even if restrictions are encountered when the parameter is specified. The parameter does not allow security to be compromised. For example, this parameter lets a user overwrite a read-only file.
Include Data type: String[]	Implement this parameter so that the user can include something in an activity. For more information about how to use input filters, see Input Filter Parameters.
Incremental Data type: SwitchParameter	Implement this parameter to indicate that processing is performed incrementally when the parameter is specified. For example, this parameter lets a user perform incremental backups that back up files only since the last backup.
InputObject Data type: Object	Implement this parameter when the cmdlet takes input from other cmdlets. When you define an InputObject parameter, always specify the ValueFromPipeline keyword when you declare the Parameter attribute. For more information about using input filters, see Input Filter Parameters.
Insert Data type: SwitchParameter	Implement this parameter so that the cmdlet inserts an item when the parameter is specified.
Interactive Data type: SwitchParameter	Implement this parameter so that the cmdlet works interactively with the user when the parameter is specified.
Interval Data type: HashTable	Implement this parameter so that the user can specify a hash table of keywords that contains the values. The following example shows sample values for the Interval parameter: -interval @{ResumeScan=15; Retry=3}.
Log Data type: SwitchParameter	Implement this parameter audit the actions of the cmdlet when the parameter is specified.
NoClobber Data type: SwitchParameter	Implement this parameter so that the resource will not be overwritten when the parameter is specified. This parameter generally applies to cmdlets that create new objects so that they can be prevented from overwriting existing objects with the same name.
Notify Data type: SwitchParameter	Implement this parameter so that the user will be notified that the activity is complete when the parameter is specified.
NotifyAddress Data type: Email address	Implement this parameter so that the user can specify the e-mail address to use to send a notification when the Notify parameter is specified.
Overwrite Data type: SwitchParameter	Implement this parameter so that the cmdlet overwrites any existing data when the parameter is specified.
Prompt Data type: String	Implement this parameter so that the user can specify a prompt for the cmdlet.
Quiet Data type: SwitchParameter	Implement this parameter so that the cmdlet suppresses user feedback during its actions when the parameter is specified.
Recurse Data type: SwitchParameter	Implement this parameter so that the cmdlet recursively performs its actions on resources when the parameter is specified.
Repair Data type: SwitchParameter	Implement this parameter so that the cmdlet will attempt to correct something from a broken state when the parameter is specified.
RepairString Data type: String	Implement this parameter so that the user can specify a string to use when the Repair parameter is specified.
Retry Data type: Int32	Implement this parameter so the user can specify the number of times the cmdlet will attempt an action.
Select Data type: Keyword array	Implement this parameter so that the user can specify an array of the types of items.
Stream Data type: SwitchParameter	Implement this parameter so the user can stream multiple output objects through the pipeline when the parameter is specified.
Strict Data type: SwitchParameter	Implement this parameter so that all errors are handled as terminating errors when the parameter is specified.
TempLocation Data type: String	Implement this parameter so the user can specify the location of temporary data that is used during the operation of the cmdlet.
Timeout Data type: Int32	Implement this parameter so that the user can specify the timeout interval (in milliseconds).
Truncate Data type: SwitchParameter	Implement this parameter so that the cmdlet will truncate its actions when the parameter is specified. If the parameter is not specified, the cmdlet performs another action.
Verify Data type: SwitchParameter	Implement this parameter so that the cmdlet will test to determine whether an action has occurred when the parameter is specified.
Wait Data type: SwitchParameter	Implement this parameter so that the cmdlet will wait for user input before continuing when the parameter is specified.
WaitTime Data type: Int32	Implement this parameter so that the user can specify the duration (in seconds) that the cmdlet will wait for user input when the Wait parameter is specified.
