그래서 어떤 천재가 인쇄 방식을 바꿨습니다. Raspbian을 사용하는 Raspberry(Debian Jessie):
$ /sbin/ifconfig eth0
eth0 Link encap:Ethernet HWaddr b8:27:eb:71:d5:56
inet addr:192.168.0.11 Bcast:192.168.0.255 Mask:255.255.255.0

내 노트북(Debian Stretch)에서:
$ /sbin/ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

랩톱에서는 분명히 실패하는 구문 분석 코드가 있습니다 . 쉘 명령을 사용하여 Raspbian/Jessie 및 Stretch에서 eth0 IP 주소를 얻는 독특한 방법이 있습니까?

이는 두 시스템 모두에서 동일한 형식을 갖습니다.
$ ip a show eth0 # stretch
