在 vim 缓冲区中的每一行上运行 vim 命令

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

Answer 3

: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.)

Answer 4

All lines to only one line

:g/^/1j
