The command "sudo firecfg" is used to configure the firewall settings on a Linux system. Here's how it works:

1. "sudo" is a command that allows a user to run commands with administrative (root) privileges. It stands for "Super User Do" and is commonly used to perform administrative tasks.

2. "firecfg" is a command that is specific to certain Linux distributions, like Fedora. It is used to manage the firewall settings of the system.

By running "sudo firecfg", you are essentially executing the "firecfg" command as the root user, which enables you to configure the firewall settings on the Linux system.

It's important to note that the availability and functionality of the "firecfg" command may vary depending on the Linux distribution you are using. Additionally, running firewall configuration commands requires administrative privileges to ensure system security.
