If /etc/redhat-release doesnot exit , echo system not running redhat or CentOS or redhat-release file is missing, then do nothing below, if /etc/redhat-release exists , then find the OS flavour and,

## if system is Redhat
OS=`cat /etc/redhat-release | awk {'print $1}'`
if [ "$OS" != "CentOS" ]
then
echo "System runs on Redhat Linux.";

do
up2date -i ncurses dialog nmap
done
exit;
fi

## if system is Centos
echo "System runs on CentOS.";
do
yum -y install ncurses dialog nmap
done



I can run the above script two times and one of them will do the install, yum or up2date. I will look better , if we use the value ( Red or CentOS ) and then build a script like ( nested or whatever you call )


If /etc/redhat-release doesnot exit , echo system not running redhat or CentOS or redhat-release file is missing, then do nothing below

else

OS=`cat /etc/redhat-release | awk {'print $1}'`
if [ "$OS" != "CentOS" ]
then
echo "System runs on Redhat Linux.";
then use the up2date command
else if system runs Centos
then use the yum comand
done

yum-debug-restore

yum-debug-restore(1)													      yum-debug-restore(1)

NAME

       yum-debug-restore - replay Yum transactions captured in a debug-dump file

SYNOPSIS

       yum-debug-restore

DESCRIPTION

       yum-debug-restore  is  a  program which takes a gzipped file created by yum-debug-dump and acts on the information about installed packages
       contained within.

GENERAL OPTIONS

       --output
	      Output the commands that would be run to stdout.

       --shell=<file>
	      Output the commands that would be run to a file.

       --install-latest
	      Ask yum to install the latest version of the given packages, instead of the version that was installed in the debug-dump file.

       --ignore-arch
	      Ignore the architecture of the packages, so you can "restore" an i386 debug-dump on an x86_64 machine.

       --filter-types=[install,remove,update,downgrade]
	      Only perform the given types of commands, so you can filter to just upgrades and installs.

FILES

       As yum-debug-restore uses YUM libraries for retrieving all the information, it relies on YUM configuration  for	its  default  values  like
       which repositories to use. Consult YUM documentation for details:

       /etc/yum.conf
       /etc/yum/repos.d/
       /var/cache/yum/

SEE ALSO

       yum-debug-dump (1)
       yum.conf (5)
       http://yum.baseurl.org/

AUTHORS

       See the Authors file included with this program.

BUGS

       There  are  of  course no bugs, but should you find any, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if
       unsuccessful in finding a resolution contact the mailing list: yum-devel@lists.baseurl.org.  To file a bug  use	http://bugzilla.redhat.com
       for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs.
