Hammer & Screwdriver Here is one apprach, although there are many ways to address this
First off, my data file (note I use pipe '|' characters between fields):
Code:
> cat sample.dat
smith|john|123-45-6789|40|usp123-45-67
jones|mary anne|111-22-1111|18|usp111-23-365
johnson|howard|333-33-3333|70|usp999-89-897

Now, the program (it does some extra displays that are more for choice):
Code:
> cat searchdata 
#! /bin/bash

echo "Enter last name"
read lname

echo "Enter first name"
read fname

echo "*****"
echo "searching for "$lname $fname
echo "*****"
matchrec=$(cat sample.dat | grep "^$lname")

if [ -n "$matchrec" ]
   then
   echo "*possible match found..." 
   ln=$(echo "$matchrec" | cut -d"|" -f1)
   fn=$(echo "$matchrec" | cut -d"|" -f2)
   if [ "$fn" = "$fname" ]
      then
      echo "*verified first name"
      ss=$(echo "$matchrec" | cut -d"|" -f3)
      ag=$(echo "$matchrec" | cut -d"|" -f4)
      pa=$(echo "$matchrec" | cut -d"|" -f5)
#display the matching data
      echo " "
      echo "First Name   :"$fn
      echo "Last Name    :"$ln
      echo "Social Sec # :"$ss
      echo "Age of person:"$ag
      echo "Passport id  :"$pa
   fi
fi

And finally, the program execution:
Code:
> searchdata
Enter last name
smith
Enter first name
john
*****
searching for smith john
*****
*possible match found...
*verified first name
 
First Name   :john
Last Name    :smith
Social Sec # :123-45-6789
Age of person:40
Passport id  :usp123-45-67

NAME

       echo, noecho - enable/disable terminal echo

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib 
       -R /usr/xpg4/lib -lcurses [ library... ]

       #include <curses.h>

       int echo(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.

ERRORS

       No errors are defined.
