Some times new packages are added to the repository, and yum ten writes Added 35 new packages, deleted 0 old in 2.58 seconds But what are these packages? yum --list gives a list of all the packages, but in alphabetical order, not by added date. So I see two possible solutions (a) --sort=date that works with --list (b) --latest-packages It would be a very useful feature, as it is likely that users would like to install some of these new programs.
check out the docs: yum list recent that should list the most recently added packages based on the package's timestamp.
