Command ReferenceA-35
NAME
exportfs - export and unexport files or directories
SYNOP SIS
exportfs [ -aiuv ] [ -o options ] [ pathname ]
DESCRIPTION
If no pathname is specified, exportfs lists all currently exported directories and
files. If pathname is specified, exportfs makes the specified file or directory avail-
able or unavailable for mounting by NFS clients.
OPTIONS
-a Takes the list of path names to be exported or unexported from the /etc/
exports file. If you specify pathname in the command when using the -a
option, the command ignores pathname.
-iIgnores the options in the /etc/exports file. Without the -i option, the
exportfs command uses the options associated with the pathname speci-
fied in /etc/exports.
-uUnexports the specified path name. If you also include the -a option, the
command unexports the path names in the /etc/exports file and ignores
pathname.
-vPrints each path name as it is exported or unexported.
-o option
Specifies a list of comma-separated options that describe how a file or direc-
tory is exported. You can specify the option in one of the following formats:
access=hostname[:hostname]...
Give mount access to each host listed. Alternatively, you can specify a net-
group instead of a host in the list. The netgroup must be defined in the /etc/
netgroup file. Whether the hosts can mount pathname with root access,
read-and-write access, or read-only access depends on how you use the
root, rw, and ro options, as described below.
anon=uid
If a request comes from user ID of 0 (root user ID on the client), use uid as
the effective user ID unless the client host is included in the root option. The
default value of uid is 65534. To disable root access, set uid to 65535. To
grant root access to all clients, set uid to 0.
ro Export the pathname read-only. If you do not specify this option, the path-
name is exported read-write.
rw=hostname[:hostname]...
Export the pathname read-only to all hosts not specified in the list and read-
write to the hosts in the list. Netgroup names are not allowed in the list.
