How to update specific repo in yum?

Question

I have multiple repos like RepoA.repo, RepoB.repo, RepoC.repo. I want to update only RepoA.repo as new RPMs will get add into it daily.
How can I update only RepoA.repo rather than using "yum update" which updates all the repos and takes long time.

Thanks, MadEngineer

There is no problem; because if no new rpms will be added to repoB and repoC; then the update will only take new rpms from repoA. If you really want to make sure that all your updates come from repoA; and none from another repository; you can just update while disabling all repositories execpt repoA:

yum --disablerepo="*" --enablerepo="repoA" update
