Run vim command on every line in a vim buffer

Question

I want to JJ on every line in the current vim buffer. As I have very huge file, it is not possible to manually run on every line. How can I tell vim to do this for me? Basically I have a file which has data in single column. I want to convert it to three columns

a
b
c

to:

a b c

Maybe duplicate of [In Vim, what is the simplest way to join all lines in a file into a single line?](http://stackoverflow.com/questions/391710/in-vim-what-is-the-simplest-way-to-join-all-lines-in-a-file-into-a-single-line) — bimlas, May 23 '14 at 05:57
@BimbaLaszlo the desired output of the question is not a single line. — Kent, May 23 '14 at 09:10
@Kent yeah, i can see now, but should rewrite the example int he question to `a \n b \n c \n d` -> `ab \n cd` — bimlas, May 23 '14 at 11:04

Simpler than mine. I guess I was tricked into thinking `:global` by the question's title. – Ingo Karkat May 23 '14 at 06:45

:g/^/join

joins consecutive lines (1+2, 3+4, and so on...) in the entire buffer. You can also supply a [range] to the :global command, which here is only used for its intelligent line handling; the ^ regular expression pattern matches any line.

To join three consecutive lines, use either

:g/^/.,.+2join

or

:g/^/join|join

(The former may give an error if the total amount of lines isn't divisible by 3; the latter avoids that.)
