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?

for

for(n)							       Tcl Built-In Commands							    for(n)

__________________________________________________________________________________________________________________________________________________

NAME

       for - 'For' loop

SYNOPSIS

       for start test next body
_________________________________________________________________

DESCRIPTION

       For  is	a  looping command, similar in structure to the C for statement.  The start, next, and body arguments must be Tcl command strings,
       and test is an expression string.  The for command first invokes the Tcl interpreter to execute start.  Then it repeatedly  evaluates  test
       as  an expression; if the result is non-zero it invokes the Tcl interpreter on body, then invokes the Tcl interpreter on next, then repeats
       the loop.  The command terminates when test evaluates to 0.  If a continue command is invoked within body then any  remaining  commands	in
       the  current  execution of body are skipped; processing continues by invoking the Tcl interpreter on next, then evaluating test, and so on.
       If a break command is invoked within body or next, then the for command will return immediately.  The operation of break and  continue  are
       similar to the corresponding statements in C.  For returns an empty string.

       Note:  test  should almost always be enclosed in braces.  If not, variable substitutions will be made before the for command starts execut-
       ing, which means that variable changes made by the loop body will not be considered in the expression.  This is	likely	to  result  in	an
       infinite loop.  If test is enclosed in braces, variable substitutions are delayed until the expression is evaluated (before each loop iter-
       ation), so changes in the variables will be visible.  See below for an example:

EXAMPLES

       Print a line for each of the integers from 0 to 10:
	      for {set x 0} {$x<10} {incr x} {
		 puts "x is $x"
	      }

       Either loop infinitely or not at all because the expression being evaluated is actually the constant,  or  even	generate  an  error!   The
       actual  behaviour  will depend on whether the variable x exists before the for command is run and whether its value is a value that is less
       than or greater than/equal to ten, and this is because the expression will be substituted before the for command is executed.
	      for {set x 0} $x<10 {incr x} {
		 puts "x is $x"
	      }

       Print out the powers of two from 1 to 1024:
	      for {set x 1} {$x<=1024} {set x [expr {$x * 2}]} {
		 puts "x is $x"
	      }
