Redhat Linux yum grouplist and groupinstall Option Not Working

last updated in Categories , , , ,

I‘m trying to install all the default packages by group using ‘yum groupinstall groupname‘ command under RHEL v5.x. But, grouplist, groupinstall, and groupdelete options are not working with yum. How do I fix this issue and make sure yum command works with software groups under Redhat Enterprise Linux to increase my productivity?
