VI command - D & x
August 10th, 2009D
The D command deletes from the cursor position to the end of the line. (D is a shortcut for d$.)
x
Often you want to delete only one or two characters. Just as r is a special change command to replace a single character, x is a special delete command to delete a single character. x deletes only the character the cursor is on.
VI command - dw&dd
August 9th, 2009dw
dw deletes a word beginning where the cursor is positioned. Notice that the space following the word is deleted.
dd
The dd command deletes the entire line that the cursor is on. dd will not delete part of a line. Like its complement, cc, dd is a special command.
VI command - (~)
August 5th, 2009~
Changing the case of a letter is a special form of replacement. The tilde (~) command will change a lowercase letter to uppercase or an uppercase letter to lowercase. Position the cursor on the letter whose case you want to change, and type a ~. The case of the letter will change, and the cursor will move to the next character.
VI command - r & s
August 4th, 2009r
One other replacement edit is given by the r command. r replaces a single character with another single character. You do not have to press ESC to return to command mode after making the edit.
s
The S command, as is usually the case with uppercase commands, lets you change whole lines. In contrast to the C command, which changes the rest of the line from the current cursor position, the S command deletes the entire line, no matter where the cursor is. vi puts you in insert mode at the beginning of the line. A preceding count replaces that many lines.
Both s and S put you in insert mode; when you are finished entering new text, press ESC.
VI command - cw&cc
August 3rd, 2009cw
To change a word, combine the c (change) command with w for word. You can replace a word (cw) with a longer or shorter word (or any amount of text). cw can be thought of as “delete the word marked and insert new text until ESC is pressed.”
cc
To replace the entire current line, use the special change command, cc. cc changes an entire line, replacing that line with any amount of text entered before pressing ESC . It doesn’t matter where the cursor is located on the line; cc replaces the entire line of text.
