This style consists of the command's name followed by the section of the manual pages in which the command description can be found, in brackets. On first occurrence such a name of a command is written in the typical Unix style. Sometimes references to Unix commands are used in this book. : range s / search / replace / options, :global / pattern / delete A Search pattern combined with an Ex command. Search pattern in vi are regular expressions.

For many Ex commands there is a long form ( :quit) and a short form ( :q). started with, followed by the command and ends with. ,, Indicates that the Shift key and the 'x' key should be pressed simultaneously, Indicates that the Meta or Alt key and the 'x' key should be pressed simultaneously. 'x' can be almost any other key on your keyboard. Indicates that the Tabulator key should be pressed, Indicates that the Control key and the 'x' key should be pressed simultaneously. Indicates that the Carrier Return (Enter) key should be pressed. , Indicates that the Escape (Esc) key on your keyboard should be pressed, which is identical to Control and '['. vi's internal high-level screen control library was later separated, and became curses - the Unix standard library for CRT screen handling.Ĭonventions A single character, such as 'a' or '1'. Because of vi's need to control the terminal and the many different types of terminals at that time, the termcap (terminal-capabilities) database was introduced (later replaced with the more flexible terminfo database).

Vi also served as a kind of incubator for Unix's terminal control capabilities. Once you are used to this, it becomes extremely convenient, because there is less movement of the hands to the cursor keys or mouse involved. The visual mode is the prevailing mode.Īlthough vi stands for visual, classic vi is mainly operated via the character keys, and not via the mouse or the cursor keys. It is also possible to choose the mode during startup. It is possible to switch between line and visual mode during editing. In fact, one can argue that the program is indeed two editors in one, one editor called vi, another called ex. ed is similar, although more powerful than edlin, which doesn't mean much. If you are still familiar with MS-DOS, then you may know the MS-DOS edlin editor. vi stands for visual and was an enormous improvement of the classic Unix editor called ed. Bill Joy later went on to co-found Sun Microsystems, and became the company's Chief Scientist at that time. It was later directly added to AT&T's System V Unix, too. Vi, pronounced like 'vee eye', was originally written by Bill Joy for BSD Unix in Berkeley in 1976 and became quickly part of many vendor-specific versions of the (at that time) original AT&T Unix. Sometimes vi is the only editor available when your computer crashes leaving a minimal system for you to repair. Even if you use another editor you must have a passing knowledge of vi as an administrator. If not the original vi, there is usually at least a good clone available that runs on your system.

Vi is a powerful editor that is ubiquitous amongst Unix and Unix-like operating systems, but is available on many other operating systems, even on MS-DOS, Windows and the Macintosh. Getting acquainted Introduction Overview The above text is a little example of how the vi editor's screen looks.
