How to use ( yumdownloader --resolve <package name> ) on ( yum -y groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts" )?

Question

As soon as I finish installing "centos-minimal" from the minimal ISO file, I need to install the GUI desktop. for this I simply run, ifup eth0, and then I run:

yum -y groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"

I would like to install all these from a local folder if possible. Here's what I know.

For example to install gcc locally I can simply create a folder named gcc on my USB stick for example. Then go into that folder and then run this command:

yumdownloader --resolve gcc

This will download everything needed to install gcc on my system, assuming that system does not yet have gcc installed. It will download all of the dependencies and so on, into the folder: gcc.

Then the next time around when I re-install CentOS minimal, I can just go into this folder and run:

yum --nogpgcheck localinstall *.rpm -y

It installs gcc as long as I'm in the "gcc" folder with all the files that were downloaded.

The question is, how to apply this to this command:

yum -y groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"

Because I don't think there is such program as:

 "Desktop" and so on.. 

What would the yum install <package name> -y equivalency be for:

yum -y groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"

because if I knew that, then I could use this:

yumdownloader --resolve <package name>

To download all the necessary packages to a folder and then install the GUI from a folder without an internet connection the next time around, when I re-installed CentOS minimal Linux.

Solution

yum's groupinfo predicate will list all the required and optional packages contained in one or more groups.

yum groupinfo Desktop "Desktop Platform" ...
