title: How to update specific repo in yum?
body: <p>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.<br>
  How can I update only RepoA.repo rather than using "yum update" which updates all the repos and takes long time.</p>
  
  <p>Thanks,
  MadEngineer</p>
