+.Nd show remote nfs mounts on host
+.Sh SYNOPSIS
+.Nm
+.Op Fl a | d
+.Op Fl E
+.Op Fl e
+.Op Fl 1
+.Op Fl 3
+.Op Ar host
+.Sh DESCRIPTION
+The
+.Nm
+utility shows status information about the
+.Tn NFS
+server on
+.Ar host .
+By default it prints the names of all hosts that have
+.Tn NFS
+file systems mounted
+on the host.
+See
+.%T "NFS: Network File System Protocol Specification" ,
+RFC 1094,
+Appendix A,
+and
+.%T "NFS: Network File System Version 3 Protocol Specification" ,
+Appendix I,
+for a detailed description of the protocol.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl a , Fl -all
+List all mount points in the form:
+.Bd -ragged -offset indent -compact
+.Ar host : Ns Ar dirpath .
+.Ed
+.It Fl d , Fl -directories
+List directory paths of mount points instead of hosts.
+.It Fl E , Fl -exports-script
+Show the
+.Ar host Ns 's
+exports list in a script-friendly format.
+Client addresses and the header are not shown, and special
+characters are escaped.
+.It Fl e , Fl -exports
+Show the
+.Ar host Ns 's
+exports list.
+.It Fl 1
+Use mount protocol Version 1, compatible with legacy servers.
+.It Fl 3
+Ignored for backwards compatibility.
+.El
+.Sh SEE ALSO
+.Xr mount 8 ,
+.Xr mount_nfs 8 ,
+.Xr mountd 8
+.Sh HISTORY
+The
+.Nm
+utility first appeared in
+.Bx 4.4 .
+.Sh BUGS
+The mount daemon running on the server only has an idea of the actual mounts,
+since the
+.Tn NFS
+server is stateless.
+The
+.Nm
+utility will only display the information
+as accurately as the mount daemon reports it.
