fs_cleanacl

FS_CLEANACL(1)						       AFS Command Reference						    FS_CLEANACL(1)

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.
