NAME


fs_cleanacl - Remove obsolete entries from an ACL

SYNOPSIS


fs cleanacl [-path <dir/file path>+] [-help]

fs cl [-p <dir/file path>+] [-h]

DESCRIPTION


The fs cleanacl command removes from the access control list (ACL) of each specified
directory or file any entry that refers to a user or group that no longer has a Protection
Database entry. Such an entry appears on the ACL as an AFS user ID number (UID) rather
than a name, because without a Protection Database entry, the File Server cannot translate
the UID into a name.

Cleaning access control lists in this way not only keeps them from becoming crowded with
irrelevant information, but also prevents the new possessor of a recycled AFS UID from
obtaining access intended for the former possessor of the AFS UID. (Note that recycling
UIDs is not recommended in any case.)

OPTIONS


-path <dir/file path>+
Names each directory for which to clean the ACL (specifying a filename cleans its
directory's ACL). If this argument is omitted, the current working directory's ACL is
cleaned.

Specify the read/write path to each directory, to avoid the failure that results from
attempting to change a read-only volume. By convention, the read/write path is
indicated by placing a period before the cell name at the pathname's second level (for
example, /afs/.abc.com). For further discussion of the concept of read/write and read-
only paths through the filespace, see the fs mkmount reference page.

-help
Prints the online help for this command. All other valid options are ignored.

OUTPUT


If there are no obsolete entries on the ACL, the following message appears:

Access list for <path> is fine.

Otherwise, the output reports the resulting state of the ACL, following the header

Access list for <path> is now

At the same time, the following error message appears for each file in the cleaned
directories:

fs: '<filename>': Not a directory

EXAMPLES


The following example illustrates the cleaning of the ACLs on the current working
directory and two of its subdirectories. Only the second subdirectory had obsolete entries
on it.

% fs cleanacl -path . ./reports ./sources
Access list for . is fine.
Access list for ./reports is fine.
Access list for ./sources is now
Normal rights:
system:authuser rl
pat rlidwka

PRIVILEGE REQUIRED


The issuer must have the "a" (administer) permission on each directory's ACL (or the ACL
of each file's parent directory); the directory's owner and the members of the
system:administrators group have the right implicitly, even if it does not appear on the
ACL.
