.\" way too many mistakes in technical documents.

.SH "NAME"
fs_cleanacl \- Remove obsolete entries from an ACL
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBfs cleanacl\fR [\fB\-path\fR\ <\fIdir/file\ path\fR>+] [\fB\-help\fR]
.PP
\&\fBfs cl\fR [\fB\-p\fR\ <\fIdir/file\ path\fR>+] [\fB\-h\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBfs cleanacl\fR command removes from the access control list (\s-1ACL\s0) 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 \s-1ACL\s0 as an \s-1AFS\s0 user \s-1ID\s0 number (\s-1UID\s0) rather than a name, because without
a Protection Database entry, the File Server cannot translate the \s-1UID\s0 into
a name.
.PP
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 \s-1AFS UID\s0 from obtaining access intended for the
former possessor of the \s-1AFS UID.\s0 (Note that recycling UIDs is not
recommended in any case.)
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-path\fR <\fIdir/file path\fR>+" 4
.IX Item "-path <dir/file path>+"
Names each directory for which to clean the \s-1ACL\s0 (specifying a filename
cleans its directory's \s-1ACL\s0). If this argument is omitted, the current
working directory's \s-1ACL\s0 is cleaned.
.Sp
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, \fI/afs/.example.com\fR). For further
discussion of the concept of read/write and read-only paths through the
filespace, see the \fBfs mkmount\fR reference page.
.IP "\fB\-help\fR" 4
.IX Item "-help"
Prints the online help for this command. All other valid options are
ignored.
.SH "OUTPUT"
.IX Header "OUTPUT"
If there are no obsolete entries on the \s-1ACL,\s0 the following message
appears:
.PP
.Vb 1
\&   Access list for <path> is fine.
.Ve
.PP
Otherwise, the output reports the resulting state of the \s-1ACL,\s0 following the
header
.PP
.Vb 1
\&   Access list for <path> is now
.Ve
.PP
At the same time, the following error message appears for each file in the
cleaned directories:
.PP
.Vb 1
\&   fs: \*(Aq<filename>\*(Aq: Not a directory
.Ve
.SH "EXAMPLES"
.IX Header "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.
.PP
.Vb 7
\&   % 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
.Ve
.SH "PRIVILEGE REQUIRED"
.IX Header "PRIVILEGE REQUIRED"
The issuer must have the \f(CW\*(C`a\*(C'\fR (administer) permission on each directory's
\&\s-1ACL\s0 (or the \s-1ACL\s0 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 \s-1ACL.\s0
