If you need to delete lines that may contain space characters (such as tabs or spaces) as well as empty ones, try:

:v/\S/d

Just an alternative.

ggqqqqq/^$dd@qq@q

Here's the other way of doing it in vim: setting a recursive macro. 'gg' brings you to the top of the buffer, 'qqq' clears the 'q' macro, 'qq' starts recording a macro called 'q', '/^$' moves the cursor to the next empty line, 'dd' deletes the line that the cursor is on, '@q' calls the 'q' macro (currently empty because of 'qqq'), and 'q' stops recording the macro. '@q' calls the macro.

It will run until it cannot find another blank line, at which point it will throw up an error and cease.

While this is longer than the regex, you can use it without having to move your thoughts from 'vim-mode' to 'regex-mode'.

Know a better way?

If you can do better, submit your command here.

What others think

':g/^\s*$/d' is two characters(three, if you count ) longer, but it doesn't highlight everything if you have 'hlsearch' on. Two extra characters saves you from possibly having to type ':nohl'

The above comment should say "(three if you count 'shift')"
