4433 라인이 아닌 443 라인만 얻으려면 어떻게 해야 합니까? 확인을 위해 변수에 둘 다 입력합니다. 문자열을 수동으로 수행하면 아래 문자열이 변수에 배치됩니다.
10.0.0.30:443 10.0.0.30:4433
반복적으로 종료되는 출력은 다음과 같습니다.
Added port forwarding for HTTPS
Nothing Altered for PrivateTTY
Nothing Altered for HTTP

대신에
grep ${mylanip}:443
하다
grep "${mylanip}:443 "
따라서 443 이후의 공백은 검색 표현식의 일부를 가져옵니다.
