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.
Does there exist any way to make the command line argument available to other function without passing them as arrguments to function?
The only way this can be achieved is by storing the command line arguments in global variables. However, this is not recommended. Global variables should only be used to represent truly global concepts, but command line arguments are local to the main function. The main function's primary role is to parse the command line arguments and invoke the appropriate functions, passing any required arguments (by value) to those functions that specifically require them. The main function's secondary role is to handle any exceptions not handled by the functions that it invokes.
