Examples
Example 1: Create an ACL object with 3 ACL entry, and update ACL on a directory
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -Permission rwx -DefaultScope
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType group -Permission rw- -InputObject $acl
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType other -Permission "rw-" -InputObject $acl
Update-AzDataLakeGen2Item -FileSystem "filesystem1" -Path "dir1/dir3" -ACL $acl

Example 2: Create an ACL object with 4 ACL entries, and update permission of an existing ACL entry
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -Permission rwx -DefaultScope
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType group -Permission rw- -InputObject $acl
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType other -Permission "rwt" -InputObject $acl
$acl = Set-AzDataLakeGen2ItemAclObject -AccessControlType user -EntityId $id -Permission rwx -InputObject $acl

False Group rw-
False Other rw-
False User ********-****-****-****-************ r-xThis command first creates an ACL object with 4 ACL entries, then run the cmdlet again with different permission but same AccessControlType/EntityId/DefaultScope of an existing ACL entry. Then the permission of the ACL entry is updated, but no new ACL entry is added.
