Several different versions of UNIX have GUI's or Graphical User Interfaces. The most common example of UNIX with an interface is Mac OS X.
The term "command line interface' is not actually used to describe an operating system, but a type of shell around an operating system. A command line interface is an interface in which you enter commands, arguments and parameters as your primary method of running programs or doing work. Depending on the operating system, the CLI may be the primary method of interfacing with the operating system. Linux (And most Unix/Unix-like systems.) can be primarily CLI driven or GUI driven, since shells are treated as just another application in those systems.
Nothing replaced it, MS-DOS is a command line interface Operating System, it is still used by Windows Operating Systems to this date, but access to it by the user has been severely limited if not completely blocked, to protect the computer from severe user error at the command line level.
Yes, but it also has a command line.

One well-known command line operating system is Linux, which is based on the Unix architecture. It provides a powerful command line interface (CLI) for users to interact with the system, execute commands, and manage files. Other examples include FreeBSD and MS-DOS, which also rely heavily on command line inputs for navigation and operations.
Because a GUI is just executing commands in the command line.
A user communicates with the operating system by using a keyboard. You can also communicate with the operating system by using a mouse.
From the command line (in windows) you can access many of windows internal features such as trouble shooting the dll structure and network analysis for more information you can type 'help' in CMD (command line) Most other operating systems have command lines, such as Linux and Ubuntu WARRNING: you can really damage your computer if you don't know what your doing
DOS is Disk Operating System. It is a command-line OS. It means you have to control the computer through codes/commands.
A shell is software that provides an interface for users of an operating system which provides access to the services of a kernel.Operating system shells generally fall into one of two categories: command-line and graphical. Command-line shells provide a command-line interface (CLI) to the operating system, while graphical shells like the Windows Shell[1][2][3] provide a graphical user interface (GUI).
