Note: We are searching for line start ( ^), followed by a line break ( \n), because we want to remove this line break, effectively deleting the empty line. However, in your case, you can use the :s command like this: g/begin/,/end/s/^\n// You would need to call :g to mark all begin/end regions, and then call another :g command to find empty lines (to be deleted).

How to delete n line from the current line in vim Say, we have 5 lines in a file and the cursor. However that means, this does not apply to your use case here. To delete the current line in vim type dd in the command mode. You can use it with the d command, to delete all lines that contain a particular. That match a pattern and do not match another pattern: :g/found/v/notfound/ The ex command g is very useful for acting on lines that match a pattern. Heres one way to move selected text over a few. When the command is used recursively, it only works on one line. After selecting the text, try d to delete, or y to copy, or :s/match/replace/, or :center, or sort, or. So you can do something like (quoting the help): Since Vim patch, one can call a recursive :g command, if it operates only within a single line.

If you now press the spacebar on your keyboard for a few times when your cursor in on those blank lines, you’ll be inserting what we call whitespaces. In the above example, all the empty lines contain only Carriage Returns, which means they are just newlines without any other characters on those lines.
