How can I add a string to the end of each line in Vim?
RegexVimReplaceMatchRegex Problem Overview
I want to add * to the end of each line in Vim.
I tried the code unsuccessfully
:%s/\n/*\n/g
Regex Solutions
Solution 1 - Regex
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
Solution 2 - Regex
:%s/$/\*/g
should work and so should :%s/$/*/g.
Solution 3 - Regex
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.
(example from Vim.Wikia.com)
Solution 4 - Regex
Also:
:g/$/norm A*
Also:
gg<Ctrl-v>G$A*<Esc>
Solution 5 - Regex
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/
Solution 6 - Regex
One option is:
>:g/$/s//*
This will find every line end anchor and substitute it with *. I say "substitute" but, in actual fact, it's more of an append since the anchor is a special thing rather than a regular character. For more information, see Power of g - Examples.
Solution 7 - Regex
You don't really need the g at the end. So it becomes:
:%s/$/*
Or if you just want the * at the end of, say lines 14-18:
:14,18s/$/*
or
:14,18norm A*
Solution 8 - Regex
...and to prepend (add the beginning of) each line with *,
%s/^/*/g
Solution 9 - Regex
:%s/\n/*\r/g
Your first one is correct anywhere else, but Vim has to have different newline handling for some reason.
Solution 10 - Regex
%s/\s*$/\*/g
this will do the trick, and ensure leading spaces are ignored.
