Every once in a while I find myself trying to install something, but not knowing what package contains it.

# yum install g++
Setting up Install Process
No package g++ available.
Error: Nothing to do

But if you’re using a modern version of yum (i.e. that of RHEL 6 or Fedora) then you can simply tell it to install the program you’re looking for.

# yum install /usr/bin/g++
Setting up Install Process
