Remarks: The line following the deleted range becomes the current line, even if the deleted range includes the last line in memory. The current line and any following lines are renumbered.
If you omit the first parameter, as in:
,lineD
deletion starts with the current line and ends with the line specified by the second parameter. The beginning comma is re- quired to indicate the omitted first parameter.
If you omit the second parameter, as in:
lineD or line,D
only the one specified line is deleted. If you omit both para- meters, as in:
D
only the current line is deleted, and the line that follows becomes the current line.
Example: Assume that you want to edit the following file. The current line is line 22.
1: This is a sample file used to demonstrate 2: line deletion and dynamic 3: line number generation. . . . . 20: See what happens to the lines 21: and line numbers when lines are 22:*deleted. 23: See how easy this is to use.
If you want to delete a range of lines, from 3-20, enter:
3,20D
The result is:
1: This is a sample file used to demonstrate 2: line deletion and dynamic 3:*and line numbers when lines are 4: deleted. 5: See how easy this is to use.
Lines 3-20 are deleted from the file. Lines 21-23 are renum- bered to 3-5. Line 3 becomes the current line. If you want to delete the current and the following line, enter:
,4D
The result is:
1: This is a sample file used to demonstrate 2: line deletion and dynamic 3:*See how easy this is to use.
Lines 3 and 4 are deleted from the file. Line 5 is renumbered to 3. Line 3 is still the current line, but now it has a dif- ferent text.
If you want to delete a single line, say line 2, enter:
2D
The result is:
1: This is a sample file used to demonstrate 2:*See how easy this is to use.
Line 2 is deleted. Line 3 is renumbered to 2. The new line 2 becomes the current line. If you want to delete only the cur- rent line, enter:
D
The result is:
1:*This is a sample file used to demonstrate
The current line, line 2, is deleted. The new line 1 becomes the current line.
