I tried with following modification and able to read user input and print them:-

Code:
#!/bin/sh
clear
echo "\t `date "+%d/%m/%Y"`"
echo "\t Hostname Machine: `hostname`"
echo "\t user: `whoami` "
echo "\t M A I N - M E N U"
echo "\t 1.Copey Directory Tree"
echo "\t 2.Delete Files or Directories"
echo "\t 3.Output Information"

while true ; do
        echo -n "\t Please enter an option [ 1 - 4 ] : "
        read opt

        case "$opt" in
                1) echo "Enter the source and destination for copying files"
                   read src
                   read dest
                   echo "$src"
                   echo "$dest"
                   ;;
                2)  ;;
                3) echo "\t the number of possible users on the system: `cat /etc/passwd |wc -l` \n\t the number of current user on the system : `who | wc -l`\n\t the number of processes running: `ps -e | wc -l`"  ;;
                *) exit ;;

done

shtool-echo

SHTOOL-ECHO.TMP(1)					      GNU Portable Shell Tool						SHTOOL-ECHO.TMP(1)

NAME

       shtool-echo - GNU shtool echo(1) extensional command

SYNOPSIS

       shtool echo [-n|--newline] [-e|--expand] string

DESCRIPTION

       shtool echo is an echo(1) style command which prints string to stdout and optionally provides special expansion constructs (terminal bold
       mode, environment details, date, etc) and newline control. The trick of this command is that it provides a portable -n option and hides the
       gory details needed to find out the environment details under option -e.

OPTIONS

       The following command line options are available.

       -n, --newline
	   By default, output is written to stdout followed by a "newline" (ASCII character 0x0a). If option -n is used, this newline character is
	   omitted.

       -e, --expand
	   If option -e is used, string can contain special "%x" constructs which are expanded before the output is written. Currently the
	   following constructs are recognized:

	   %B  switch terminal mode to bold display mode.

	   %b  switch terminal mode back to normal display mode.

	   %u  the current user name.

	   %U  the current user id (numerical).

	   %g  the current group name.

	   %G  the current group id (numerical).

	   %h  the current hostname (without any domain extension).

	   %d  the current domain name.

	   %D  the current day of the month.

	   %M  the current month (numerical).

	   %m  the current month name.

	   %Y  the current year.

EXAMPLE

	#   shell script
	shtool echo -n -e "Enter your name [%B%u%b]: "; read name
	shtool echo -e "Your Email address might be %u@%h%d"
	shtool echo -e "The current date is %D-%m-%Y"

HISTORY

       The GNU shtool echo command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Website META Language (WML)
       under the name buildinfo. It was later taken over into GNU shtool.
