Which command would you use to install software on a Linux system?

The command to use for installing software on a Linux system is "sudo yum install." This command is part of the YUM package manager, which is predominantly used in Red Hat-based distributions like CentOS, Fedora, and RHEL. When you issue this command, you are instructing the system to run the YUM package manager with superuser privileges (due to the "sudo" prefix), enabling you to install the specified software package from the repositories configured on the system.

Using "sudo yum install [package-name]" fetches the necessary files, resolves dependencies, and installs the software package, making it an essential tool for managing software in Linux environments that utilize YUM. This is crucial for maintaining up-to-date systems and managing applications efficiently.

In this context, the other commands do not serve the purpose of installing software. "sudo apt-get remove" is used for uninstalling software in Debian-based systems, "sudo service start" is employed to start services rather than install software, and "sudo netstat" is a command for displaying network connections and does not pertain to software installation.
