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 Built : CentOS Buildsys <bugs@centos.org> at Thu 19 Dec 2019 03:44:23 PM GMT Installed: rpm-0:4.14.2-25.el8.x86_64 at Mon 23 Mar 2020 10:59:10 AM GMT Built : CentOS Buildsys <bugs@centos.org> at Fri 08 Nov 2019 10:56:14 PM GMT
NOTE:
root user to run all the below commands.You can use any user with sudo access to run all these commands. For more information Please check Step by Step: How to Add User to Sudoers to provide sudo access to the User.Example 2: How to Update Your System Using DNF Command
If you want to update your System then you need to use dnf update command as shown below. This command will search and install all the latest updates from Enabled Repositories.

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 7 | -y groupupdate Core Mini | 2020-03-23 07:19 | Install | 46 ## 6 | install -y kernel-core | 2020-03-23 07:17 | Install | 1 5 | -y --releasever=8 --allo | 2020-03-23 06:56 | D, E, I, O, U | 617 E< 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 Last metadata expiration check: 0:08:09 ago on Wed 01 Jul 2020 10:47:34 PM EDT.
