How to Loopback?

This is in the beginning of the program:

Code:
clear
tput cup 1 20
echo "Welcome to UNIX I Final Assignment"
tput cup 4 3
echo -e "Who would you like to look up?  \c"
tput cup 6 5
echo "[E]vans, Rolland"
tput cup 8 5
echo "[J]ones, Mildred"
tput cup 10 5
echo "[S]mith, Julie"
tput cup 12 5
echo "[Z]ane,  Morris"
tput cup 14 5
echo "Press [Ctrl + c] in Your Keyboard to Quit"
tput cup 16 3
echo -e "Please Enter Your Choice : \c"
tput cup 17 3
echo "(It Is NOT Case Sensitive, Please Feel Free to Make Any Input)"
read option
case $option in

I also created the corresponding information for each input on the display so...

My question is...
How do I display the corresponding information for 5 second and then loop back to the main menu?

NAME
ticlts, ticots, ticotsord - loopback transport providers SYNOPSIS
#include <sys/ticlts.h> #include <sys/ticots.h> #include <sys/ticotsord.h> DESCRIPTION
The devices known as ticlts, ticots, and ticotsord are ``loopback transport providers,'' that is, stand-alone networks at the transport level. Loopback transport providers are transport providers in every sense except one: only one host (the local machine) is ``connected to'' a loopback network. Loopback transports present a TPI (STREAMS-level) interface to application processes and are intended to be accessed via the TLI (application-level) interface. They are implemented as clone devices and support address spaces consisting of ``flex- addresses,'' that is, arbitrary sequences of octets of length > 0, represented by a netbuf structure. ticlts is a datagram-mode transport provider. It offers (connectionless) service of type T_CLTS. Its default address size is TCL_DEFAULTAD- DRSZ. ticlts prints the following error messages (see t_rcvuderr(3NSL)): TCL_BADADDR bad address specification TCL_BADOPT bad option specification TCL_NOPEER bound TCL_PEERBADSTATE peer in wrong state ticots is a virtual circuit-mode transport provider. It offers (connection-oriented) service of type T_COTS. Its default address size is TCO_DEFAULTADDRSZ. ticots prints the following disconnect messages (see t_rcvdis(3NSL)): TCO_NOPEER no listener on destination address TCO_PEERNOROOMONQ peer has no room on connect queue TCO_PEERBADSTATE peer in wrong state TCO_PEERINITIATED peer-initiated disconnect TCO_PROVIDERINITIATED provider-initiated disconnect ticotsord is a virtual circuit-mode transport provider, offering service of type T_COTS_ORD (connection-oriented service with orderly release). Its default address size is TCOO_DEFAULTADDRSZ. ticotsord prints the following disconnect messages (see t_rcvdis(3NSL)): TCOO_NOPEER no listener on destination address TCOO_PEERNOROOMONQ peer has no room on connect queue TCOO_PEERBADSTATE peer in wrong state TCOO_PEERINITIATED provider-initiated disconnect TCOO_PROVIDERINITIATED peer-initiated disconnect USAGE
Loopback transports support a local IPC mechanism through the TLI interface. Applications implemented in a transport provider-independent manner on a client-server model using this IPC are transparently transportable to networked environments. Transport provider-independent applications must not include the headers listed in the synopsis section above. In particular, the options are (like all transport provider options) provider dependent. ticlts and ticots support the same service types (T_CLTS and T_COTS) supported by the OSI transport-level model. ticotsord supports the same service type (T_COTSORD) supported by the TCP/IP model.
