Paste in multiple files with one command in VIM

Question

Let's say i have opened 10 HTML files horizontally in VIM by using

vim -o *.html

I would like to delete the last portion of the files by using range of lines and the windo command to apply it to all windows:

:windo :55, $ d

Now, I have yanked new content and would like to paste in all files using one cmd(maybe with the help of windo again) instead of going 1 by 1 file.

What are your suggestions?

P.S. I would prefer to do it in VIM instead of using shell cmd.

thanks in advance,

Answer 1

:windo $pu

will paste your yanked text (" register) to each window, after the last line.
