To install the "wget" utility on a RHEL or CentOS system using the "yum" package manager, you can use the following command:
yum install wget
This will install the "wget" package and all of its dependencies.
If the "wget" package is not available in the default repositories, you may need to enable additional repositories or add a custom repository before you can install the package. You can use the "yum repolist" command to list the available repositories, and the "yum-config-manager" command to enable or disable repositories.
For example, to enable the "EPEL" repository on a CentOS 7 system, you can use the following command:
yum-config-manager --enable epel
Then, you can use the "yum install" command to install the "wget" package from the enabled repository.
Keep in mind that you may need to use "sudo" to run the "yum" commands with root privileges, depending on your system configuration.
For example:
sudo yum install wget
This will install the "wget" utility on your RHEL or CentOS system. You can then use the "wget" command to download files from the internet.
