Remove-AzDataLakeGen2AclRecursive cmdlet 以递归方式删除指定路径上的 ACL。 原始 ACL 中的 ACL 条目，该条目具有相同的 AccessControlType、DefaultScope 和 EntityId 以及输入 ACL 条目（即使具有不同权限）wil lbe 已删除。

$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -EntityId $id -Permission r-x -DefaultScope
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -EntityId $id -Permission r-x -InputObject $acl
Remove-AzDataLakeGen2AclRecursive -FileSystem "filesystem1" -Acl $acl -Context $ctx
WARNING: To find the ACL Entry to remove, will only compare AccessControlType, DefaultScope and EntityId, will omit Permission.

FailedEntries                   :
TotalDirectoriesSuccessfulCount : 7
TotalFilesSuccessfulCount       : 5
TotalFailureCount               : 0
ContinuationToken               :

此命令首先创建包含 2 个 acl 条目的 ACL 对象，然后在文件系统的根目录上以递归方式删除 ACL。

$result = Remove-AzDataLakeGen2AclRecursive -FileSystem "filesystem1" -Path "dir1" -Acl $acl  -Context $ctx
WARNING: To find the ACL Entry to remove, will only compare AccessControlType, DefaultScope and EntityId, will omit Permission.

此命令首先以递归方式删除目录上的 ACL 并失败，然后在用户修复失败的文件后继续使用 ContinuationToken。

此脚本将以分块方式以递归方式删除目录区块，区块大小为 BatchSize * MaxBatchCount。 此脚本中的区块大小为 50000。

$result = Remove-AzDataLakeGen2AclRecursive -FileSystem "filesystem1" -Path "dir1" -Acl $acl -ContinueOnFailure -Context $ctx

$result

FailedEntries                   : {dir0/dir1/file1, dir0/dir2/file4}

            Remove-AzDataLakeGen2AclRecursive -FileSystem "filesystem1" -Path $path -Acl $acl -Context $ctx
        }

此命令首先以递归方式删除具有 ContinueOnFailure 的目录，某些项失败，然后逐个恢复失败的项目。

此 cmdlet 支持通用参数：-Debug、-ErrorAction、-ErrorVariable、-InformationAction、-InformationVariable、-OutBuffer、-OutVariable、-PipelineVariable、-ProgressAction、-Verbose、-WarningAction 和 -WarningVariable。 有关详细信息，请参阅 about_CommonParameters。
