Access Control Lists

An Access Control List (ACL) stores a series of entries that identify specific users or groups and their access privileges for a directory or file. A file may have its own ACL or may share an ACL with other files. ACLs have the advantage of specifying detailed access permissions for multiple users and groups. Refer to the getacl(1) and setacl(1) manual pages for information on viewing and setting ACLs. For VxFS file systems created with the Version 5 disk layout, up to 1024 ACL entries can be specified. ACLs are also supported on cluster file systems.
