In this exercise, you'll install the Z shell software package using the dnf tool on your CentOS server.

1 Log into your CentOS server as the root user account, using the password you created in Chapter 4, “Installing a Red Hat Server.”

2 From the command prompt, enter the command dnf install zsh. You should see output that's similar to this:# dnf install zsh CentOS-8 - AppStream 2.4 kB/s | 4.3 kB 00:01 CentOS-8 - AppStream 883 kB/s | 6.2 MB 00:07 CentOS-8 - Base 154 B/s | 3.9 kB 00:25 CentOS-8 - Base 865 kB/s | 2.3 MB 00:02 CentOS-8 - Extras 2.3 kB/s | 1.5 kB 00:00 CentOS-8 - Extras 8.3 kB/s | 8.1 kB 00:00 Dependencies resolved. ============================================================================= Package Architecture Version Repository Size ============================================================================= Installing: zsh x86_64 5.5.1-6.el8_1.2 BaseOS 2.9 M Transaction Summary ============================================================================= Install 1 Package Total download size: 2.9 M Installed size: 7.2 M Is this ok [y/N]: y Downloading Packages: zsh-5.5.1-6.el8_1.2.x86_64.rpm 392 kB/s | 2.9 MB 00:07 ------------------------------------------------------------------------------ Total 362 kB/s | 2.9 MB 00:08 Running transaction check Transaction check succeeded.

3 Test the installation by entering the command zsh. You will see a prompt from the new Z shell. If you receive an error message, something went wrong.

4 Return to the Bash Shell by entering the command exit.

5 Check whether the installation processed properly by entering the command dnf list installed zsh. You should see the package appear, as shown here: # dnf list installed zsh Installed Packages zsh.x86_64 5.5.1-6.el8_1.2 @BaseOS #
