# Script name : pingnmap
# Scenario : The systems admin in company X is tired of the monotonous job
# of pinging and nmapping, so he decided to simplify the job using a script.
# The tasks he wish to achieve is
# 1. Ping - with a max count of 5 -the given IP address/domain. AND/OR
# 2. Check if a particular port is open with a given IP address/domain.
# And getopts is for her rescue.
# A brief overview of the options
# n : meant for nmap
# t : meant for ping
# i : The option to enter the IP address
# p : The option to enter the port
# v : The option to get the script version

while getopts ':nti:p:v' opt
#putting : in the beginnnig suppresses the errors for invalid options
