Cmdleten Remove-AzDataLakeGen2AclRecursive tar bort ACL rekursivt på den angivna sökvägen. ACL-posterna i den ursprungliga ACL:n, som har samma AccessControlType, DefaultScope och EntityId med indata-ACL-poster (även med olika behörighet) kommer att tas bort.

$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -EntityId $id -Permission r-x -DefaultScope
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -EntityId $id -Permission r-x -InputObject $acl

WARNING: To find the ACL Entry to remove, will only compare AccessControlType, DefaultScope and EntityId, will omit Permission.

Det här kommandot skapar först ett ACL-objekt med 2 acl-poster och tar sedan bort ACL rekursivt i en rotkatalog i ett filsystem.
