[J]
Sometimes while editing a file you will end up with a series of
short lines that are difficult to scan.
When you want to merge two lines into one, position the cursor
anywhere on the first line, and press J
to join the two lines.
Suppose your file practice reads:
With a screen editor you can scroll the page, move the cursor |
Keystrokes | Results |
---|---|
J | With a screen editor you can scroll the page, move the cursor |
| |
. | With a screen editor you can scroll the page, move the cursor |
Repeat the last command ( |
Using a numeric argument with J
joins that number
of consecutive lines.
In the example above, you could have joined three lines by using
the command 3J
.
When you type commands, text jumps around on the screen and nothing works the way it's supposed to.
Make sure you're not typing the J
command when you mean j
.
You may have hit the
[CAPS LOCK]
key without noticing it.
vi is case-sensitive. That is, uppercase commands (I
,
A
, J
, etc.) are different from lowercase commands
(i
, a
, j
), so all your commands are being
interpreted not as lowercase but as uppercase commands.
Press the
[CAPS LOCK]
key again to return to lowercase, then type either U
to restore the
last line changed or u
to undo the last command.
You'll probably also have to do some additional editing to fully
restore the garbled part of your file.
