Show all versions of a package using yum

allversyum.txt

I needed to determine all the different versions of a package that came from repositories I had set up on a server.
I knew there was at least two versions of java-1.8.0-openjdk but I wanted to be sure.
I found the following command and it did the job perfectly:

[root@hwwn3 ~]# yum --showduplicates list java-1.8.0-openjdk | expand
Loaded plugins: product-id, search-disabled-repos, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Available Packages
java-1.8.0-openjdk.ppc64le 1:1.8.0.65-3.b17.el7  xcat-otherpkgs0                
java-1.8.0-openjdk.ppc64le 1:1.8.0.102-4.b14.el7 local-rhels7.3-ppc64le--install-rhels7.3-ppc64le
java-1.8.0-openjdk.ppc64le 1:1.8.0.102-4.b14.el7 xCAT-rhels7.3-path0

Here is the url where I discovered this command.  You have to look carefully for the command.
