List repositories
=================

List subscription repos::

  sudo subscription-manager repos --list

List enabled repositories::

  sudo dnf repolist
  sudo dnf repolist --enabled

List disabled repositories::

  sudo dnf repolist --disabled

Activate repository::

  sudo subscription-manager repos --enable $REPO

List packages
=============

List all installed packages::

  dnf repoquery --installed

List packages selected by a user (but not automatically to meet dependenciy requirements)::

  dnf repoquery --userinstalled
  dnf history userinstalled

List packages in a repository::

  dnf repository-packages $REPO list

Search for a package::

  dnf search nodejs

List all package version::

  dnf search --showduplicates nodejs

List all package versions together with repos::

  dnf list --showduplicates nodejs

Check package details
=====================

Check if a package is installed::

  dnf list $PKG
  rpm --verify $PKG
  rpm -V $PKG

Check a package version::

  dnf info $PKG

Check repository/origin availability::

  dnf whatprovides $PKG

List package's files
====================
::

  dnf repoquery -l $PKG
  rpm -ql $PKG

Find packages a file belongs to
===============================

Using remote metadata::

  dnf provides ifconfig
  dnf repoquery --file /usr/sbin/ifconfig
  repoquery --whatprovides python3
  repoquery --whatprovides libssl*.so.*

Using installed package DB::

  rpm -qf /usr/bin/rpm
  rpm -q --whatprovides /bin/bash

Limit search to a specific repository::

  dnf repoquery --disablerepo=* --enablerepo=$REPO -f $PATT

List package dependencies
=========================
::

  dnf deplist $PKG
  repoquery --requires --resolve $PKG

If you possess an actual RPM (``-q`` or ``--query``, ``-R`` or ``–requires``)::

  rpm -qpR $RPM

List of packages that depend on a given
=======================================
::

  dnf repoquery --alldeps --whatrequires $PKG
  dnf repoquery --installed --whatrequires $PKG
  rpm -q --whatrequires $PKG

Install package
===============

By package name::

  dnf install $PKG

By a package file::

  rpm -i $PKG.rpm
  rpm --install $PKG.rpm

Update a package by a file (same as install but removes all earlier versions)::

  rpm -U $PKG.rpm
  rpm --upgrade $PKG.rpm

Dealing with streams
====================

Streams group related package at specific compatible version. Only one version could be installed in
system in time.

For example Node.js has lots of parallel versions::

  bash# sudo dnf module list nodejs
  Name   Stream Profiles                              Summary
  nodejs 10 [d] common [d], development, minimal, s2i Javascript runtime
  nodejs 12     common [d], development, minimal, s2i Javascript runtime
  nodejs 14     common [d], development, minimal, s2i Javascript runtime
  nodejs 16     common [d], development, minimal, s2i Javascript runtime
  nodejs 18     common [d], development, minimal, s2i Javascript runtime

You select specific stream::

  sudo dnf module install nodejs:18

In order to change stream one need to remove all the packages from original stream and reset the
stream::

  sudo dnf module remove nodejs
  sudo dnf module reset nodejs
  sudo dnf module install nodejs:16

Extra Packages for Enterprise Linux
===================================

EPEL stands for Extra Packages for Enterprise Linux and you can enable them by installing a special
package::

  sudo dnf install epel-release
  sudo dnf install epel-next-release
