Thanks.  Much different output than I got from Fedora.  What are all 
those + in front of each line?

the recommendation on how to feed a list into yum from:

https://unix.stackexchange.com/questions/47304/centos-install-packages-listed-in-a-text-file

yum -y install $(cat filename cat | tr '\n' ' ')

Will need a bit more editing of the list than just removing the first lines!

hmm. but that seems like an error with 'cat filename cat'  ??
