sed "."를 탈출하고 $variable을 사용하시겠습니까?

나는 이런 회피를 이해하지 못한다. 발전기가 있나요?

일반 텍스트(185...)를 $NEW_DNS 변수로 바꿔야 합니다.

sed -i "185.228.168.168,185.228.169.168|$NEW_DNS /etc/wireguard/wg0.conf

산출

sed: -e expression #1, char 4: unknown command: `.'

업데이트: 답변을 확인하고 작동하길 바랍니다. /etc/wireguard/wg0.conf가 새 데이터로 다시 작성되지 않았다는 것입니다(그러나 출력은 정확합니다.
