The first three lines of the output do not hold any information not available with
ls -l
. These lines only state filename, owner, and owning group. Lines 4 to
9 hold the ACL entries. Conventional access permissions represent a subset of
those possible when using ACLs. The example ACL grants read and write ac-
cess to the owner of the file as well as to user
those possible when using ACLs. The example ACL grants read and write ac-
cess to the owner of the file as well as to user
jane
(lines 4 and 5). The conven-
tional concept has been expanded allowing access to an extra user. The same ap-
plies to the handling of group access. The owning group holds read permissions
(line 6) and the group
plies to the handling of group access. The owning group holds read permissions
(line 6) and the group
djungle
holds read and write permissions. The
mask
en-
try in line 8 reduces the effective permissions for the user
jane
and the group
djungle
to read access. Other users and groups do not get any kind of access to
the file (line 9).
Only very basic information has been provided here. Find more detailed informa-
tion about ACLs in the Administration Guide.
