호스트를 ping하고 존재하는지 확인한 다음 쉘 스크립트를 통해 결과를 파일로 보냅니다.

Windows에서 사용자 정의 파일을 정리 hosts하고 데드존을 제거하기 위해 호스트에 ping을 보내고 domains.txt응답을 받으면 호스트를 다음에 추가합니다 result.txt.

@echo off

>result.txt (
    for /f %%i in (domain.txt) do ping -n 1 %%i >nul && echo 127.0.0.1 %%i
)

누구든지 Linux 쉘 스크립트를 통해 동일한 기능을 달성하도록 도와줄 수 있습니까?

답변1

을 사용하는 경우 bash다음과 같은 짧은 스크립트를 사용해 볼 수 있습니다.

#!/bin/bash
while IFS= read -r host; do
    [[ $(ping -c4 "$host") ]] 2>/dev/null && echo "$host" >> /path/to/result.txt
done < /path/to/domains.txt

여기서는 호스트가 개행 문자로 구분되어 있다고 가정합니다 domains.txt.

편집하다:

다음은 수정된 스크립트이며, ping자세한 내용(요약)이며 디렉터리에 /path/to/directory/파일 domains-01.txt등이 domains-02.txt포함되어 있다고 가정합니다.

#!/bin/bash
for file in /path/to/directory/domains-*.txt; do
    while IFS= read -r host; do
        ping -qc4 "$host" && echo "$host" >> /where/to/save/result.txt
    done < "$file"
done

일시 중지-재개 동작을 원하면 다음을 확인하세요.SIGTSTP/ SIGSTOP및 SIGCONT신호kill예를 들어 프로세스의 PID가 2773인 경우 유사한 명령을 실행할 수 있습니다 .

일시중지: kill -TSTP 2773, 재개: kill -CONT 2773.

의도한 대상이 아니더라도 무엇이든 에코를 가로채서 응답할 수 있기 때문에 핑을 피하려고 합니다. 이것이 내가 사용하는 것입니다:
