Question

我一直在尝试将两个查询合并为一个。我正在尝试获取IP信息的输出，该输出将与针对主机文件的另一个查询进行比较，并最终转储到数据库中。由于它们的部署方式，我的命令必须是简单的一个衬里。我可以用这两个得到我需要的东西，但有没有办法将它们结合起来。 ip show输出了多行输出，但不确定如何组合这些行。

ip -o addr show | awk '/inet/ {print $9, $4}' | grep -v '127.0.0.1'
ip -o addr show | awk '/link/ {print $2, $13}' | grep -v lo

Top提供大部分信息，bottom提供mac。这给了两个但它是多行的，所以不知道如何唤醒我需要的值。有什么好的想法或窍门？在linux / bash上还是新的。

 ip -o addr show | grep -i 'ether\|inet'

ip -o addr show命令的示例

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN \            link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Answer 1

尝试使用egrep而不是grep

Answer 2

这不是原始的100％准确，但它适用于您的输入：

ip -o addr show | awk '/inet/ && !/127.0.0.1/ {print $9, $4} /link/ && ! /lo/ {print $2, $13}'

如果你想在一行输出，那么你可以像{i}这样在echo $(...)包装上面的命令：

echo $(ip -o addr show | awk '/inet/ && !/127.0.0.1/ {print $9, $4} /link/ && ! /lo/ {print $2, $13}')

Linux One Liner返回eth名称，ip，mac和子网
