ACL Entries for Directories

In addition to the ACL entries described in Table 17-8, you can set default ACL entries on a directory. Files or directories created in a directory that has default ACL entries will have the same ACL entries as the default ACL entries. The table below lists the default ACL entries for directories.

When you set default ACL entries for specific users and groups on a directory for the first time, you must also set default ACL entries for the file owner, file group, others, and the ACL mask (these are required and are the first four default ACL entries in the table below).

Table 17-9 Default ACL Entries for Directories

d[efault]:g[roup]::perms	Default file group permissions.
d[efault]:o[ther]:perms	Default permissions for users other than the file owner or members of the file group.
d[efault]:m[ask]:perms	Default ACL mask.
d[efault]:u[ser]:uid:perms	Default permissions for a specific user. For uid, you can specify either a user name or a numeric UID.
d[efault]:g[roup]:gid:perms	Default permissions for a specific group. For gid, you can specify either a group name or a numeric GID.
