You could probably try doing something like this:
Code:
find /root/Desktop/chandu -name *.rpm --exec echo rpm -Uvh {} ;/
This would find any filename in /root/Desktop/chandu with .rpm at the end of the file, it would then echo out the commands to update the packages (I'm sure when you issue the -U flag if the package is not installed then it will install anyway). I normally run this command with the echo after the exec to see what will be run. When I am sure that it is doing what I need it to do I remove the echo and see what happens. If you run the above and post back your results I can have a look if you would like me to.
