# Shell script utility to read a file line line version 2
# This is simpler version of readline script
# This script also demonstrate how to process data file
# line by line and then separate line in fields, so that
# you can process it according to your need.
#
# You can call script as follows
# ./readline2

### Main script stars here ###
# Store file name  here
FILE="/etc/passwd"
# field seprator, default is :, you can use blank space or
# other character, if you have more than one blak space in
# input line then use awk utility and not the cut :)
