Yeah, I think I need to rewrite that sentence. Without applying `tac`, the task is about matching the last occurrence. After applying `tac`, the task changes to matching the first...

Thanks for letting me know, I'll fix them in the next version. I think I have many more such comma spliced run-on sentences.

Thanks, I'll mention it in the next update. I do mention this SO thread (https://stackoverflow.com/questions/45420535/whats-the-most-robust-way-to-efficiently-parse-csv-using-awk) as well as an alternate option, but yours is aimed to work with other tools...

I don't understand what you mean by `GNU sed` treats blank lines differently. By default, `sed` works only line by line. So, you cannot match across multiple lines unless you...

oops, clicked "close" issue by mistake.

```bash $ echo foo | sd '\w+' '$$a' $a ``` * You need to use `\w+` to match one or more word characters. `w+` will match one or more `w`...

Just checked the help page and seems it isn't documented. I knew about `$$` from using `ripgrep`. Perhaps you could submit the PR.
