以Set-Acl为例，简述参数类型

PS C:\Users\admin> Get-Help Set-Acl 名称 Set-Acl 摘要 Changes the security descriptor of a specified item, such as a file or a registry key. 语法 Set-Acl [-Path] [-AclObject] [[-CentralAccessPolicy] ] [-ClearCentralAccessPolicy] [-Exclude ] [-Filter ] [-Include ] [-Passthru] [-UseTransaction] [-Confirm] [-WhatIf] [] Set-Acl [-AclObject] [[-CentralAccessPolicy] ] [-ClearCentralAccessPolicy] [-Exclude ] [-Filter ] [-Include ] -LiteralPath [-Passthru] [-UseTransaction] [-Confirm] [-WhatIf] [] Set-Acl [-InputObject] [-AclObject] [-Exclude ] [-Filter ] [-Include ] [-Passthru] [-UseTransaction] [-Confirm] [-WhatIf] [] 说明 The `Set-Acl` cmdlet changes the security descriptor of a specified item, such as a file or a registry key, to match the values in a security de scriptor that you supply. To use `Set-Acl`, use the Path or InputObject parameter to identify the item whose security descriptor you want to change. Then, use the AclObje ct or SecurityDescriptor parameters to supply a security descriptor that has the values you want to apply. `Set-Acl` applies the security descri ptor that is supplied. It uses the value of the AclObject parameter as a model and changes the values in the item's security descriptor to match the values in the AclObject parameter. 相关链接 Online Version: https://docs.microsoft.com/powershell/module/microsoft.powershell.security/set-acl?view=powershell-5.1&WT.mc_id=ps-gethelp Get-Acl FileSystemAccessRule ObjectSecurity.SetAccessRuleProtection FileSystemRights 备注 若要查看示例，请键入: "get-help Set-Acl -examples". 有关详细信息，请键入: "get-help Set-Acl -detailed". 若要获取技术信息，请键入: "get-help Set-Acl -full". 有关在线帮助，请键入: "get-help Set-Acl -online"
