How to Check the Size og yum Channels in CentOS/RHEL

Question: How to find out how large a yum channel repository is, to know how much data the channel will sync to a local yum repository?

To see the actual size of the repository use either the ‘yum repolist -v‘ or ‘yum repoinfo‘ command.

Example for checking the size of “CentOS-8 – AppStream” yum channel

Run the command as shown below to get the size of the Repo “CentOS-8 – AppStream”. The command works even without the double quotes around the repo name.

# yum repoinfo "CentOS-8 - AppStream"

Example for checking the size of all enabled yum channels

Another command to view the size of all the yum repos configured on the system is “yum repolist -v”. The -v option verbosely prints all the information for all the repos inclusing their sizes.

# yum repolist -v
