我正在尝试从一些 VM 获取前 3 行 ip address/ifconfig - 其中一些在 Ubuntu 上运行,其中一些在 CentOS 上。
例如:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9001
inet 172.31.106.100 netmask 255.255.240.0 broadcast 172.31.111.255
inet6 fe80::10c5:1dff:fec0:803e prefixlen 64 scopeid 0x20<link>
ether 12:c5:1d:c0:80:3e txqueuelen 1000 (Ethernet)
RX packets 7483 bytes 7706844 (7.3 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 2998 bytes 470781 (459.7 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1000 (Local Loopback)
RX packets 12100 bytes 3865475 (3.6 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 12100 bytes 3865475 (3.6 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
从这行代码中,我只需要得到以下部分:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9001
inet 172.31.106.100 netmask 255.255.240.0 broadcast 172.31.111.255
inet6 fe80::10c5:1dff:fec0:803e prefixlen 64 scopeid 0x20<link>
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
这同样适用于 ip address 命令。有什么方法可以使用 Linux 命令来实现这一点?
非常感谢,
