Guide to Installing Commands on CentOS

When a Windows user switches to Linux the first thing is to understand the command line structure and how to install software in Linux. Most users use the CentOS operating system. CentOS is a widely used Linux distribution based on Red Hat Enterprise Linux (RHEL). It is popular for its stability, security, and reliability, making it a good choice for servers and other critical systems.

In this post, we will learn how to install commands on CentOS. Several types are discussed below so user can choose according to their needs.

How to Install Commands

One of the great things about CentOS is that it is very easy to install commands. There are several ways to do this, depending on your needs and preferences.

1. Yum Package Manager

The Yum package manager is the most common way to install commands on CentOS. It is a very powerful and versatile tool that allows you to install, remove, and update packages from the CentOS repositories. To install a command using Yum, you simply need to run the following command:

sudo yum install <package_name>

For example, to install the “which” command, you would run the following command:

sudo yum install which -y

The “-y” option tells Yum to install the package without prompting you for confirmation.

2. DNF Package Manager

DNF is a newer package manager that is available in CentOS 8 and later. It is designed to be faster and more efficient than Yum. To install a command using DNF, you simply need to run the following command:

sudo dnf install <package_name>

For example, to install the “which” command, you would run the following command:

sudo dnf install which -y

3. RPM Package Manager

RPM is the lowest-level package manager for Red Hat-based distributions. It is used to install, remove, and manage individual RPM packages. To install a command using RPM, you need to download the RPM package for the command you want to install. You can then install the package using the following command:

sudo rpm -i <package_name.rpm>

For example, to install the “which” command, you would need to download the following RPM package. You can then install the package using the following command:

sudo rpm -i which-2.22-1.el7.rpm

4. Flatpak package

Flatpak is a new way to install and manage applications on Linux. Flatpak packages are self-contained and include all of the dependencies that the application needs to run. This means that you can install and run Flatpak applications without having to install any additional dependencies. To install a command using Flatpak, you first need to install the Flatpak runtime. You can do this by running the following command:

sudo yum install flatpak -y

Once the Flatpak runtime is installed, you can add the Flathub repository to your system. Flathub is a repository that contains a wide variety of Flatpak applications. You can add the Flathub repository by running the following command:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Once the Flathub repository has been added, you can install the command using the following command:

flatpak install flathub <package_name>

Easy Methods to Install Commands

The following easy methods are discussed below if you are a fan of GUI but not interested in installing commands via the command line interface and also want to download via repository.

1. Graphical User Interface

If you are not comfortable using the command line, you can also install commands using the GUI. To do this, simply open the software application and search for the command you want to install. Once you have found the command, click on the Install button.

2. Third-Party Repository
