'''3. Which file stores the static hostname to IP address mapping ?'''
/etc/sysconfig/networking/profiles/default/hosts
How about: Static mappings of hostnames to IP addresses are stored in the file '/etc/hosts'.
'''4. Which file stores the DNS servers IP addresses ?'''
/etc/sysconfig/networking/profiles/default/resolv.conf I think DNS server IP addresses are stored in the file is: '/etc/resolv.conf'.
'''5. What information is stored in /etc/sysconfig/network file ?'''

CHALLENGEROption #1: There is no need to use tar or xargs to accomplish this task. It can be performed in it's entirety by the 'find' command. Assuming you have used a command like shown in the answer for question #8 to find all files in /etc/ modified by a particular GUI change, you could modify the command to copy all the located files to your current directory using the following form:  find /etc/ -type f -cnewer ~/stamp --exec cp {} . \; ''- Katherine Masseau''

'''8. A simpler way to find the files modified by a change made in the system configuration GUI:'''
If you are trying to determine what files in the /etc/ directory were modified by a particular configuration change made in the GUI, the simplest method is the following:
1. Before you make the alteration to the GUI settings, run the following command in your shell of choice:
'touch ~/timestamp'
This command creates an empty file in your home directory named timestamp. We don't need to put anything in this file - the only important part is the modification time.
3. Now, return to your shell of choice and run the following command:
'find /etc/ -cnewer ~/timestamp'
This command will return a list of files in the /etc/ directory that have been modified more recently than the file '~/timestamp', making it much easier than attempting to calculate the correct time by hand using the other time related switches for the find command.
