Linux commands are the instructions used to communicate with the Linux operating system. They are entered into a terminal or console and perform various functions, such as navigating the file system, managing processes, controlling user permissions, and more. Linux commands can be combined with pipes, filters, and redirections to perform complex tasks, and can also be easily automated and scripted.
