Using vi :s to swap a captured word to end of line

In VI I have a series of lines like al xxe fl e ~ ] ~ stand ~ sneak ~ w ~ slit % That I'd like to look like this: al xxe ] ~ stand ~ sneak ~ w ~ slit % ~ fl e It's only 8 lines, so I'll probably do it by hand before I get an answer, but it's the principle of the thing. I've learned a lot about :s recently and feel like I should be able to do this. Another thing of note, I'm doing this in VSCode and some of the particulars of :s are different. This is what I'm trying to do :86,95s/(fl\w{1,2})/$ ~ \1/ Where I think $ should put me at EOL, but it just puts a $ where the pattern was matched. Thanks!
