Which command is used to install a specific package?

• A. apt show
• B. apt search
• C. apt install
• D. apt update

Answer: (C)

The command used to install a specific package on a system that uses the Advanced Packaging Tool (APT) is 'apt install'. This command directly facilitates the installation of packages from Debian-based distributions, such as Ubuntu. When you execute 'apt install' followed by the package name, the APT package management system retrieves the package from the repositories, resolves dependencies, and installs it on your system. Using 'apt show' provides detailed information about a particular package, such as its description, dependencies, and installed version, but does not perform the installation. The 'apt search' command is utilized for searching available packages in the repository based on keywords but does not install anything. Lastly, 'apt update' refreshes the local package index with the latest information about available packages and their versions from the repositories but does not install or update any packages. Therefore, 'apt install' is the appropriate command for directly installing packages.
