emacs 26.1, windows 10
I have some text. I need to replace all text before WARN
I use:
query-replace-regexp: .*WARN
query replace regexp: RET
But I need to delete all text BEFORE WARN. How I can do this?
here is the result:

Do you want to delete the whole line up to the WARN?– A_PFeb 15, 2019 at 16:26

may I suggest few alternative solutions: 1. You can define a keyboard macro as follows: C-x ( C-s WARN Ent M-b C-Space C-a C-w C-x ) This will give a macro that does what you need for first occurring line with WARN. Then just C-u 50 C-x e to do the same macro 50 times. 2. install multiple-cursors (and you should anyways) select WARN and then do mc/select-next-like-this (bind it to something easy) keep selecting and then just edit all lines with WARN as if you were editing a single line.– A_PFeb 15, 2019 at 17:07

@A_P I known about multi cursors. I use them. But I want to solve this task by regexp.– a_subscriberFeb 15, 2019 at 17:17

emacs must be doing something under the covers. none of these solutions work stackoverflow.com/questions/2013124/…– A_PFeb 15, 2019 at 17:35

To remove the text before WARN, just enter WARN as the replacement text. That is, use WARN as your input to the second prompt.
