dnf - Dandified YUM and is basically an improved version of the YUM package manager.
In more recent systems, both yum and dnf actually link to the same executable, dnf-3 – so it does not matter which one is used.
$ sudo subscription-manager repos --enable codeready-builder-for-rhel-9-$(arch)-rpms
$ sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
This will download the repository file to /etc/yum.repos.d/epel.repo and enables it.
on RHEL 8 it is required to also enable the codeready-builder-for-rhel-8-*-rpms repository since EPEL packages may depend on packages from it:
ARCH=$( /bin/arch )
sudo subscription-manager repos --enable "codeready-builder-for-rhel-8-${ARCH}-rpms"
$ sudo dnf repolist epel
$ sudo dnf repolist epel -v
$ sudo dnf repolist epel
$ sudo dnf --disablerepo="*" --enablerepo="epel" list available # List packages available on EPEL repository.
$ sudo dnf --disablerepo="*" --enablerepo="epel" list available | grep <package>
$ sudo dnf --disablerepo="*" --enablerepo="epel" list available | grep chromium
$ sudo dnf repository-packages epel list
$ sudo dnf repository-packages epel list | grep -i zabbix
$ sudo dnf --enablerepo="epel" install <package>

$ dnf –enablerepo=”epel” install <pkg_name>
$ sudo dnf --enablerepo="epel" install neofetch -y
