I performed an install of "java-devel". Several packages got installed. So far so good.
Yet, when I performed  yum list installed | grep java-devel and also  yum rpm -qa | grep java-devel
it did not show up as already installed.
This behavior appears both on Centos7 and Centos6. This bothers me because as a time-saving effort, I maintain the last output of "yum list installed" and quickly determine whether it's worth running yum. True, yum would "do nothing", but that takes several seconds.
Is there some simple explanation? It works for all the other packages I've installed.
There is a java-1.7.0-openjdk-devel or java-1.7.0-openjdk-devel, but no java-devel
True, but then how does "yum install java-devel" know what to install without a package by that name? I thought that the "yum install" command took package (or group) names.
And sorry about the error in my rpm command; I meant it without the "yum" in front of it. David
