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

I tried the code unsuccessfully

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

From stackoverflow

• :%s/$/\*/g

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

  MrWiggles : +1. No need to escape the asterisk in the replacement tho

  dirkgently : Yup. More readable to me with one, though.

  MrWiggles : I won't argue, you have an awesome username so that gets you kudos points ;-)

  Aman Jain : Is there a way to insert '*' at the same column, since all lines are not of same length, so line 1 might have '*' at 15th column, but line 2 has '*' at 25th column.

• %s/\s*$/*/g

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

• :%s/\n/*\r/g

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

  Nathan Fellman : In my version of Vim \n works, but this just replaces the newline with a *, effectively joining the lines.

  Ant P. : This command is verified to work fine on every version of Vim I've tried. Are you using the windows version or something?

• Note there is no need for the trailing 'g' as only one replacement is possible.

  : "as only one replacement is possible" *per line*

  Masi : Thank you Neil! Simplicity is always beautiful :)

• Another option no-one has mentioned is

  :g/$/s//*

  Masi : What does s// mean in the regex? I know a similar command, :g/ / /p, (grep). I am pretty sure that your command is close to mine, at least in the structure.

  paxdiablo : The s is substitute - it replace the end of line anchor with the asterisk (well, not actually replaces it since it's an anchor point).

• Also:

  :g/$/norm A*
  

  Also:

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

• 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
  

  smcameron : Man, there exists no vi or vim thread from which I do not learn something. Today I learn about norm. And as they say at Cheers, "Norm!"

  Nathan Fellman : Ditto - voted up for "norm"
