답변:
귀하의 IP 범위에는 대칭이 없으며 노드가 10 개뿐이므로 텍스트 파일에 나열하는 것이 좋습니다. 목록이 포함 된 파일은 list.txt
아래 표시된 것처럼 각 줄에 ip 목록이 포함되어 있다고 생각합니다 .
10.12.13.14
172.15.48.3
192.168.45.54

예를 들어 ./script 192.168.1 0 10을 실행하려면 ips 192.168.1.0 ~ 192.168.1.10을 확인하고 ping이 정상이면 에코가 응답하고 그렇지 않으면 응답하지 않습니다.
주의 : 범위와 IP가 항상 같은 경우 $ 1 $ 2 $ 3을 정적 변수로 대체 할 수 있습니다.
5 개의 IP가 있다고 가정하고 (답변 만 줄이기 위해) 핑할 수 있습니다
#!/usr/bin/bash
for i in xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxxx
do
ping -c 5 $i
done
참고 : 괄호 안, IP 사이에 쉼표 (,) 없음.
희망이 도움이됩니다.
