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.
