31 Useful DNF Command examples for RPM Package Management in Fedora/RHEL/CentOS

Table of Contents

In this article, I will take you through 31 Useful DNF Command Examples for RPM Package Management in Fedora/RHEL/CentOS. If you are a Linux Professional then you might be aware of yum command which is being used frequently to download packages, update or upgrade packages etc till RHEL/CentOS 7 but from RHEL/CentOS 8 there is a new tool called DNF comes up replaced legacy YUM tool. DNF is also known as Dandified YUM which is considered as next generation tool for RPM Package Management in Linux. In this session, we will go through multiple examples of DNF Command to understand its usages in RPM Package Management in Linux.

Example 1: How to Check DNF Command Version

If you want to check dnf tool version then you need to use dnf --version command as shown below. As you can see from below output, current dnf command version is 4.2.7.

[root@localhost ~]# dnf --version
4.2.7
Installed: dnf-0:4.2.7-7.el8_1.noarch at Mon 23 Mar 2020 11:02:17 AM GMT

Example 3: How to Install a Package Using dnf command in Linux

If you want to install a package then you need to use below dnf command. In this example, we are trying to install unzip package using dnf install unzip command. This command will find and install the latest available version of unzip package from Repository.

Example 4: How to Check DNF Command History

If you want to check all the dnf command history then you need to use dnf history command as shown below. This command is very similar to history command that you are very much familiar with. This is very useful command in determining what you ran in the past particularly when you got into some kind of dnf command related error.

[root@localhost ~]# dnf history
ID|     Command line         |   Date and time  | Action(s)     | Altered
-------------------------------------------------------------------------------
8 | install nodejs           | 2020-07-01 21:19 | I, U          | 8

6 | install -y kernel-core   | 2020-03-23 07:17 | Install       | 1

4 | upgrade -y epel-release  | 2020-03-23 06:49 | Upgrade       | 1 >
3 | upgrade -y http://mirror | 2020-03-23 06:47 | I, U          | 3 EE
2 | -y upgrade               | 2020-03-23 06:30 | E, I, U       | 55 EE
1 | -y remove yum yum-metada | 2020-03-23 06:27 | Removed       | 4

Example 5: How to Install a Package Assuming Yes as Answer 

If you want to install a package assuming yes as answer for the confirmation then you need to use -y option with dnf command as shown below. In this example, we are trying to install httpd package using dnf install httpd -y command.

[root@localhost ~]# dnf install httpd -y

Example 7: How to Check all Enabled and Disabled Repo List Using DNF Command

If you want to check all enabled as well as disabled repo then you need to use dnf repolist all command as shown below. This dnf command will not only show the enabled but disabled repository as well. This is very helpful in determining which repo is currently enabled and which one are not.

[root@localhost ~]# dnf repolist all

Example 8: How to Check for Available Updates using DNF Command

If you want to check all available updates then you  need to use dnf check-update command as shown below. This dnf command will only show the available updates, it will not install any updates. So that you can choose if you want to install any specific updates rather than installing all of them.

[root@localhost ~]# dnf check-update
