如何获取所有接口并关联 IP 地址,如下所示
[root@centso ]# ifconfig
enp3s0f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet addr:10.5.2.10 Bcast:10.5.7.255 Mask:255.255.248.0

我想要如下输出,我也相信有一个命令ip link
或其他东西可以做到这一点,但不记得了,而且有些机器的网卡名称不同,例如enoX
或ethX
enp3s0f0: 10.5.2.10
enp3s0f1:
enp4s0f0:
enp4s0f1:
答案1
我想我发现了一些东西,我确信一定有更聪明的方法,但现在我已经准备好了。
[root@server1 ~]# ip -o -4 addr show | awk '{print $1" " $2": "$4}'
1: lo: 127.0.0.1/8
2: eno1: 192.168.100.190/24
3: eno2: 10.5.8.33/21
答案2
尝试这个:
ip addr show | awk -F '[: ]+' '
/^[^ ]/ { iface=$2 } # Start of section, we memorize the interface name
$2 == "inet" { print iface ": " $3 } # IPv4 address => print the line
'
答案3
有一个例子:
ip address show | awk '/inet / {split($2,var,"/*"); print $7,":",var[1]}'
输出应该是这样的:
: 127.0.0.1
enp3s0f0: 10.5.2.10
enp3s0f1: .......
enp4s0f0: .......
enp4s0f1: .......
答案4
此命令显示所有接口及其各自的 IP 地址,在一行中以空格分隔
ip r|grep " src "|cut -d " " -f 3,12 | xargs
