Chapter 8 - YUM - script to list status of repositories

I guess I'm bored. "Chapter 8 - What is YUM" talks about the repository files in /etc/yum.repos.d. In my Centos VM there are quite a number of them. As it turns out, some of these repository files contain definitions for multiple repos.

Instead of printing each one and check for enabled=1, I wrote this little one-liner that lets you know which repositories are enabled:

for i in /etc/yum.repos.d/*; do echo "$i: "; cat $i | grep -e "\[" -e enabled= ; done

Hope it's useful.

    no need for a script. This is a dnf command
    sudo dnf repolist --all (or --disabled or --enabled) as in
    sudo dnf repolist --all

    which generates 199 lines of output on my RHEL 8 system (CentOS I'm sure would be less) and you can easily
    grep out the enabled or disabled lines as in:

    [email protected]:/etc/yum.repos.d>dnf repolist --all | grep enabled

    Nice. @coop It's a good idea to install dnf "manually" in Centos 7 (yum install dnf)?, because this package manager was included starting from the Centos 8.

    there is no dnf on CentOS 7, it appears only in CentOS 8 (and much earlier versions of Fedora). ON CentOS 8 you can use yum, it is simply a wrapper around dnf as for basic commands the syntax is identical. But one should probably get out of the habit of typing yum and just do dnf.

    I am so used to yum, so I even use it on my Fedora laptop... Will be a shocker when CentOS 8 comes around for my servers...

    To repeat, the yum command works fine on CentOS 8. It is now a wrapper around dnf. I'm sure you can find corner cases where it doesn't work for advanced purposes, but mostly you would be missing out on some new enhancements. So it is not a need to instantly redo everything.
