UNIX may be described as being difficult to use Why?
Traditionally, the UNIX command interface was the only way to communicate within a UNIX system. Today, that is not true, with the graphical interfaces that are available. However, the true power of what you can do within UNIX is still in the command line interface. The command line interface is not very intuitive, and uses commands that are abbreviated to the point of not necessarily being understandable. Also, system administration tasks in Unix have typically been harder to accomplish because of the amount of background knowledge necessary even to do simple things. UNIX was developed early on for programmers by programmers, and little thought was given to the end user; as a result, it had a reputation of being difficult to use until you took the time to understand the (admittedly) arcane command line interface.

Why is Unix called a command interpreter?
Unix and Unix-like systems would be referred to as command interpreters because of the nature of their interface. These systems are interacted with via a shell (i.e. Bash), which is a 'command-line interface' where the user types in text commands and they are executed by the system. This is in contrast with modern operating systems where the primary method of interaction is via a 'graphical user interface' or GUI, where the system is represented with graphics (like windows, cursors, toolbars etc.). These modern OS's still include command-line interfaces, like Command Prompt in Windows and the Terminal in OSX.
