Mac OS X is designed to give users all the power of an industry-standard UNIX-based operating system without having to know anything about BSD (Berkeley Software Distribution) tools. From an administrator and technical coordinator's perspective, however, you may find it convenient to use a command-line interface to accomplish certain administrative or troubleshooting tasks. Using the command-line interface is optional, but for the purposes of obtaining Apple Help Desk Essentials certification, it is necessary to understand the basics of when, where, and how to use these tools.

Sometimes referred to in UNIX environments as a shell, a command-line interface executes commands entered as text rather than from a menu selection or mouse click. The shell is the traditional interface to a UNIX system, and many features of Mac OS X can be accessed only as commands on the command line.

When you are shopping for a new car, one of the decisions you have to make is whether you want an automatic or manual transmission. Both types of transmission have advantages and disadvantages. Ultimately, your needs and preferences determine which you select.

Like selecting a transmission, the decision to use the graphical or the command-line interface depends upon your needs and preferences. Native Mac OS X applications, such as the Finder, simplify your computer experience, handling many tasks automatically. The command line allows you a greater degree of manual control and configuration of your computer. In Mac OS X, unlike a car, you don't have to chooseyou have both interfaces to use whenever you need them.

TIP

As you become more comfortable with the command-line interface, you will use it more frequently for configuration and troubleshooting. However, when assisting others with troubleshooting, you should use the graphical utilities whenever possible; in these circumstances use the command-line only when absolutely necessary.
