Thanking you Komal Access Control Lists refers to a method of giving fine-grained access to files and directories. The user, group and other method of access control that the standard Linux filesystems use is too coarse in many circumstances. So when you have, for instance, a file in which you want to grant read access to some users, write to other users and similarly read and write to specific groups, you can use a filesystem with ACLS. Using ACLs you can define the following (from my experience with XFS): - - Read, write and execute permissions for user and group of file and others. This is the standard Unix file permission paradigm. - - User and group masks that will be automatically applied to new permissions. The masks consist of r,w and x bits. If a bit is off in the mask, the corresponding permission will not be enabled on fresh ACLs even if the ACL explicitly requests it. - - A list of users and groups. r, w and x permissions can be granted to each user and group in the list on an individual basis. - - Directories also have a ``default'' ACL, which consists of the three items above and which is automatically applied to all new files created under that directory. This is sort of equivalent to the ``Inherit permissions'' feature on Winduhs. As far as I can make out the (now defunct) POSIX 1003.1e standard for ACLs does not support the concept of default ACLs.
