showmount lists all the clients that have
remotely mounted a filesystem from host. This
information is maintained by the
mountd(NADM)
server on host and is saved across crashes in the
file /etc/rmtab. The default value for
host is the host name returned by
hostname(TC).
Options
-d
list directories that have been remotely mounted by clients
-a
print all remote mounts in the format
hostname:directory
where hostname is the name of the client and
directory is the root of the filesystem that has
been mounted
-e
print the list of exported filesystems
Limitations
If a client crashes, its entry will not be removed from the
list until it reboots and actually umounts the filesystem.
