yum:tldr:57586

The command "yum -y install ${package}" is a Linux command used to install a package/package group specified by the variable "package" using the YUM package manager.

Here's a breakdown of each part of the command:

• "yum" is the command-line package management utility used in many Linux distributions, including CentOS and Fedora.
• "-y" is an option used with the yum command that automatically answers "yes" to any prompts or confirmation messages that may appear during the installation process. This ensures that the installation continues without requiring user intervention.
• "install" is a yum command used to specify that the following argument(s) should be installed on the system.
• "${package}" is a variable that should be replaced with the name of the package or package group you want to install. This variable allows for dynamic package installation by providing the package name as an argument without modifying the actual command.

In summary, the command "yum -y install ${package}" installs the specified package or package group using yum without asking for any user confirmation. The actual package to install should be assigned to the variable "package" before running the command.
