I need more time to think about it.

sorry, it was closed by accident.

Hi, @ksperling Thanks for your PR, it's indeed a bug. The following 2 case can both grep successfully: ```sh root@localhost# echo "api.example.com" | grep "api.example.com" api.example.com root@localhost# echo "api-example.com" |...

@ksperling can you please try these code ? ```bash root@st:~# d=api.example.com root@st:~# echo "api.example.com" | grep "^${d//./\.}" api.example.com root@st:~# echo "api-example.com" | grep "^${d//./\.}" api-example.com ``` There is no difference.

please merge the latest code.

fixed, try again please: ``` acme.sh --upgrade -b dev ```

`grep -i` is ok. can you update this PR ?

sorry, it was closed by accident.

please rebase the code first. there are too many changes.

Is this change compatible with the existing acme.sh users? I mean the existing certs can renew without any changes?
