NAME¶

lfc-getacl - get LFC directory/file access control lists

SYNOPSIS¶

lfc-getacl [-a] [-d] path...

DESCRIPTION¶

lfc-getacl gets the Access Control List associated with a LFC directory/file. For each path, it displays the file name, owner, the group, and the Access Control List (ACL) if present. If a directory has a default ACL, lfc-getacl also displays the default ACL. Regular files cannot have default ACLs. The output looks like:

     # file: filename
     # owner: username
     # group: groupname
     user::perm
     user:uid:perm
     group::perm
     group:gid:perm
     mask:perm
     other:perm
     default:user::perm
     default:user:uid:perm
     default:group::perm
     default:group:gid:perm
     default:mask:perm
     default:other:perm

The first "user" entry gives the permissions granted to the owner of the file. The following "user" entries show the permissions granted to specific users, they are sorted in ascending order of uid. The first "group" entry gives the permissions granted to the group owner of the file. The following "group" entries show the permissions granted to specific groups, they are sorted in ascending order of gid. The "mask" entry is the maximum permission granted to specific users or groups. It does not affect the "owner" and "other" permissions. The "mask" entry must be present if there are specific "user" or "group" entries. "default" entries associated with a directory are inherited as access ACL by the files or sub-directories created in that directory. The umask is not used. Sub-directories also inherit the default ACL as default ACL. As soon as there is one default ACL entry, the 3 default ACL base entries (default user, default group, default other) must be present. The entry processing conforms to the Posix 1003.1e draft standard 17.

path

specifies the LFC pathname. If path does not start with /, it is prefixed by the content of the LFC_HOME environment variable.

uid

is displayed as the username if known else as the numeric id.

gid

is displayed as the groupname if known else as the numeric id.

perm

is expressed as a combination of characters rwx-
