3) Allocate print space for story text, photos, and illustrations according to space parameters and copy significance, using knowledge of layout principles. 4) Plan the contents of publications according to the publication's style, editorial policy, and publishing requirements. 5) Verify facts, dates, and statistics, using standard reference. Vi (pronounced 'vee-eye') is short for 'vi'sual editor. It displays a window into the file being edited that shows 24 lines of text. Vi is a text editor, not a 'what you see is what you get' word processor. Vi lets you add, change, and delete text, but does not provide such formatting capabilities as centering lines or indenting paragraphs. The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

The vi editor is available on almost all Unix systems. vi can be used from any type of terminal because it does not depend on arrow keys and function keys--it uses the standard alphabetic keys for commands.

This help note explains the basics of vi:

  • opening and closing a file
  • moving around in a file
  • elementary editing

vi has many other commands and options not described here. The following resources can help you get started using the vi editor, and are available at the UW University Book Store:

  • 'vi Reference.' Specialized Systems Consultants (SSC).

Starting vi

You may use vi to open an already existing file by typing

where 'filename' is the name of the existing file. If the file is not in your current directory, you must use the full pathname.

Or you may create a new file by typing

where 'newname' is the name you wish to give the new file.

On-screen, you will see blank lines, each with a tilde (~) at the left, and a line at the bottom giving the name and status of the new file:

~

vi Modes

vi has two modes:

  • command mode
  • insert mode

In command mode, the letters of the keyboard perform editing functions (like moving the cursor, deleting text, etc.). To enter command mode, press the escape key.

In insert mode, the letters you type form words and sentences. Unlike many word processors, vi starts up in command mode.

Entering Text

In order to begin entering text in this empty file, you must change from command mode to insert mode. To do this, type

Nothing appears to change, but you are now in insert mode and can begin typing text. In general, vi's commands do not display on the screen and do not require the Return key to be pressed.

Type a few short lines and press at the end of each line. If you type a long line, you will notice the vi does not word wrap, it merely breaks the line unceremoniously at the edge of the screen.

If you make a mistake, pressing or may remove the error, depending on your terminal type.

Moving the Cursor

To move the cursor to another position, you must be in command mode. If you have just finished typing text, you are still in insert mode. Go back to command mode by pressing . If you are not sure which mode you are in, press once or twice until you hear a beep. When you hear the beep, you are in command mode.

The cursor is controlled with four keys: h, j, k, l.

When you have gone as far as possible in one direction, the cursor stops moving and you hear a beep. For example, you cannot use l to move right and wrap around to the next line, you must use j to move down a line. See the section entitled 'Moving Around in a File' for ways to move more quickly through a file.

Basic Editing

Editing commands require that you be command mode. Many of the editing commands have a different function depending on whether they are typed as upper- or lowercase. Often, editing commands can be preceded by a number to indicate a repetition of the command.

Deleting Characters

To delete a character from a file, move the cursor until it is on the incorrect letter, then type

The character under the cursor disappears. To remove four characters (the one under the cursor and the next three) type

To delete the character before the cursor, type

Deleting Words

To delete a word, move the cursor to the first letter of the word, and type

This command deletes the word and the space following it.

To delete three words type

Deleting Lines

To delete a whole line, type

The cursor does not have to be at the beginning of the line. Typing dd deletes the entire line containing the cursor and places the cursor at the start of the next line. To delete two lines, type

To delete from the cursor position to the end of the line, type

Replacing Characters

To replace one character with another:

  1. Move the cursor to the character to be replaced.
  2. Type r
  3. Type the replacement character.

The new character will appear, and you will still be in command mode.

Replacing Words

To replace one word with another, move to the start of the incorrect word and type

The last letter of the word to be replaced will turn into a $. You are now in insert mode and may type the replacement. The new text does not need to be the same length as the original. Press to get back to command mode. To replace three words, type

Replacing Lines

To change text from the cursor position to the end of the line:

  1. Type C (uppercase).
  2. Type the replacement text.
  3. Press .

Appending Text

Opening a Blank Line

To insert a blank line below the current line, type

Joining Lines

To join two lines together:

  1. Put the cursor on the first line to be joined.

  2. Type 3J

Undoing
