How can I add a string to the end of each line in Vim?

Question

I want to add * to the end of each line in Vim.

I tried the code unsuccessfully

:%s/\n/*\n/g

Answer 1

:%s/$/\*/g

should work. So should :%s/$/*/g as MrWiggles points out correctly.

Answer 2

Even shorter than the :search command:

:%norm A*

This is what it means:

 %       = for every line
 norm    = type the following commands
 A*      = append '*' to the end of current line

Answer 3

Also:

:g/$/norm A*

Also:

gg<Ctrl-v>G$A*<Esc>

Answer 4

I think using visual block mode is a better and more versatile method for dealing with this type of thing. Here's an example:

This is the First line.
This is the second.
The third.

To insert " Hello world." (space + clipboard) at the end of each of these lines:

• On a character in the first line, press Ctrl-V (or Ctrl-Q if Ctrl-V is paste).
• Press jj to extend the visual block over three lines.
• Press $ to extend the visual block to the end of each line. Press A then space then type Hello world. + then Esc.

The result is:

This is the First line. Hello world.
This is the second. Hello world.
The third. Hello world.

Answer 5

If u want to add Hello world at the end of each line:

:%s/$/HelloWorld/

If you want to do this for specific number of line say, from 20 to 30 use:

:20,30s/$/HelloWorld/

If u want to do this at start of each line then use:

:20,30s/^/HelloWorld/

Answer 6

...and to prepend (add the beginning of) each line with *,

%s/^/*/g

Answer 7

You don't really need the g at the end. So it becomes:

:%s/$/*

Or if you just want the * at the end of, say lines 14-18:

:14,18s/$/*

or

:14,18norm A*

Answer 8

One option is:

:g/$/s//*

This will find every line end anchor and substitute it with *. I say "substitute" but, in actual fact, it's more of an append since the anchor is a special thing rather than a regular character. For more information, see Power of g - Examples.

Answer 9

:%s/\n/*\r/g

Your first one is correct anywhere else, but Vim has to have different newline handling for some reason.

Answer 10

%s/\s*$/\*/g

this will do the trick, and ensure leading spaces are ignored.
