+.Nm
+.Op Fl 46clu
+.Op Fl f Ar address_family
+.Op Fl p Ar ports
+.Sh DESCRIPTION
+The

+command lists open Internet or
+.Ux
+domain sockets.
+.Pp
+The following options are available:
+.Bl -tag -width Fl
+.It Fl 4
+Show
+.Dv AF_INET
+(IPv4) sockets.
+.It Fl 6
+Show
+.Dv AF_INET6
+(IPv6) sockets.
+.It Fl c
+Show connected sockets.
+.It Fl f Ar address_family
+Limit listed sockets to those of the specified
+.Ar address family .
+The following address families
+are recognized:
+.Ar inet ,
+for
+.Dv AF_INET ;
+.Ar inet6 ,
+for
+.Dv AF_INET6 ;
+and
+.Ar local
+or
+.Ar unix ,
+for
+.Dv AF_LOCAL .
+.It Fl l
+Show listening sockets.
+.It Fl p Ar ports
+Only show Internet sockets if either the local or foreign port number
+is on the specified list.
+The
+.Ar ports
+argument is a comma-separated list of port numbers and ranges
+specified as first and last port separated by a dash.
+.It Fl u
+Show
+.Dv AF_LOCAL
+.Pq Ux
+sockets.
+.El
+.Pp
+If neither
+.Fl 4 , 6
+or
+.Fl u
+is specified,
+.Nm
+will list sockets in all three domains.
+.Pp
+If neither
+.Fl c
+or
+.Fl l
+is specified,
+.Nm
+will list both listening and connected sockets, as well as those
+sockets that are in neither state.
+.Pp
+The information listed for each
+socket is:
+.Bl -tag -width "FOREIGN ADDRESS"
+.It Li USER
+The user who owns the socket.
+.It Li COMMAND
+The command which holds the socket.
+.It Li PID
+The process ID of the command which holds the socket.
+.It Li FD
+The file descriptor number of the socket.
+.It Li PROTO
+The transport protocol associated with the socket for Internet
+sockets, or the type of socket (stream or datagram) for
+.Ux
+sockets.
+.It Li LOCAL ADDRESS
+For Internet sockets, this is the address the local end of the socket
+is bound to (see
+.Xr getsockname 2 ) .
+For bound
+.Ux
+sockets, it is the socket's filename or
+.Dq - .
+.It Li FOREIGN ADDRESS
+The address the foreign end of the socket is bound to (see
+.Xr getpeername 2 )
+or
+.Dq -
+for unconnected
+.Ux
+sockets.

+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Fx 3.1 .
+It was then rewritten for
+.Nx 3.0 .
