Vim delete blank lines
VimViVim Problem Overview
What command can I run to remove blank lines in Vim?
Vim Solutions
Solution 1 - Vim
:g/^$/d
:g will execute a command on lines which match a regex. The regex is 'blank line' and the command is :d (delete)
Solution 2 - Vim
Found it, it's:
g/^\s*$/d
Source: Power of g at vim wikia
>Brief explanation of :g
>
> :[range]g/pattern/cmd
>
>This acts on the specified [range] (default whole file), by executing the Ex command cmd for each line matching pattern (an Ex command is one starting with a colon such as :d for delete). Before executing cmd, "." is set to the current line.
Solution 3 - Vim
:v/./d
or
:g/^$/d
or
:%!cat -s
Solution 4 - Vim
The following can be used to remove only multi blank lines (reduce them to a single blank line) and leaving single blank lines intact:
:g/^\_$\n\_^$/d

-
how to remove all the blanks lines
:%s,\n\n,^M,g
(do this multiple times util all the empty lines went gone)
-
how to remove all the blanks lines leaving SINGLE empty line
:%s,\n\n\n,^M^M,g
(do this multiple times)
-
how to remove all the blanks lines leaving TWO empty lines AT MAXIMUM,
:%s,\n\n\n\n,^M^M^M,g
(do this multiple times)
in order to input ^M, I have to control-Q and control-M in windows
Solution 6 - Vim
How about:
:g/^[ \t]*$/d
Solution 7 - Vim
This works for me
:%s/^\s*$\n//gc
Solution 8 - Vim
work with perl in vim:
:%!perl -pi -e s/^\s*$//g
Solution 9 - Vim
This function only remove two or more blank lines, put the lines below in your vimrc, then use \d to call function
fun! DelBlank()
let _s=@/
let l = line(".")
let c = col(".")
:g/^\n\{2,}/d
let @/=_s
call cursor(l, c)
endfun
map <special> <leader>d :keepjumps call DelBlank()<cr>
Solution 10 - Vim
I tried a few of the answers on this page, but a lot of them didn't work for me. Maybe because I'm using Vim on Windows 7 (don't mock, just have pity on me :p)?
Here's the easiest one that I found that works on Vim in Windows 7:
:v/\S/d
Here's a longer answer on the Vim Wikia: http://vim.wikia.com/wiki/Remove_unwanted_empty_lines
Solution 11 - Vim
:g/^\s*$/d
^ begin of a line
\s* at least 0 spaces and as many as possible (greedy)
$ end of a line
paste
:command -range=% DBL :<line1>,<line2>g/^\s*$/d
in your .vimrc,then restart your vim. if you use command :5,12DBL it will delete all blank lines between 5th row and 12th row. I think my answer is the best answer!
Solution 12 - Vim
Press delete key in insert mode to remove blank lines.
Solution 13 - Vim
If something has double linespaced your text then this command will remove the double spacing and merge pre-existing repeating blank lines into a single blank line. It uses a temporary delimiter of ^^^ at the start of a line so if this clashes with your content choose something else. Lines containing only whitespace are treated as blank.
%s/^\s*\n\n\+/^^^\r/g | g/^\s*$/d | %s/^^^^.*
Solution 14 - Vim
This worked for me:
:%s/^[^a-zA-Z0-9]$\n//ig
It basically deletes all the lines that don't have a number or letter. Since all the items in my list had letters, it deleted all the blank lines.
