Because (GUIs) have become very easy to use in the past decade or so, it is no longer common for most computer users to utilize the command line, especially for simple tasks such as word processing, searching the web and sending e-mail.
Thus, the command line is frequently perceived as being unnecessary, intimidating and even obsolete. A GUI is a display mode that contains images, and menus and which is manipulated primarily with a mouse. However, the command line, also referred to as the (although the shell is actually a the provides the command line), can be quite easy to learn and use, and its value soon becomes apparent after a little practice. Even a basic familiarity with it can make computers easier to use and facilitate performing tasks that might be difficult or impossible with a GUI. Such familiarity can also lead to an improved understanding of how computers actually work. Many people who are new to the command line will be familiar with the command line used in and think that the two are similar.

The Linux command line is far more powerful (i.e., it is much more flexible and can do many more things), and in some ways it is much more user friendly. Studying the Linux command line provides an education in much more than just how to use a specific operating system. One reason is that the Linux command line is virtually identical to the command line used on every other operating system, e.g., Solaris, FreeBSD and Mac OS X. Thus, multiple operating systems are being learned simultaneously. Studying the command line also provides insight into how computers really work.
This is because the command line is much closer to the internal functioning of computers than are GUIs, which are generally just front ends for the used on the command line. Moreover, the underlying commands typically have greater flexibility than their GUI counterparts, they can easily be combined with other commands, and they can be used in situations where a GUI is not available (e.g., making system repairs) or is not functioning properly.
Accessing the Command Line A first step in learning about the command line is accessing it. Usually, the easiest way to do this is to open a, which is an all-text window in a GUI. This can be accomplished by merely clicking on the appropriate menu item or (i.e., small image). For example, in the case of Red Hat Linux, all that is necessary is to select the item called Terminal which appears in the System Tools menu. Usb 2.0 hub driver.

The easiest way to accomplish this is to simultaneously press the CRTL, ALT and F1 keys while in a GUI.
