Linux一行程序返回eth名称、ip、mac和子网

我一直在尝试将两个查询合并为一个查询。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。我的命令必须是简单的一行程序，因为它们是如何部署的。我可以用这两种方法得到我所需要的，但是有没有办法把它们结合起来。ip show输出多行输出，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

顶部提供大部分信息，底部获得mac。这两者都有，但它是多行的，所以不确定如何提取出我需要的值。有什么好的想法或技巧吗？在linux/bash上仍然是新的

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

ip-oaddrshow命令的示例

尝试使用egrep而不是grep

ip -o addr show | egrep -i "ether|inet" 

---

这不是100%的准确度，但它与您的输入相符：

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

如果要在一行上输出， 然后可以将上述命令包装在

echo$（…）

中，如下所示：

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

---

这会在ip-o addr show上返回相同的值，但会丢失第一条环回行。这肯定更接近我所寻找的。但仍然是多行输出。我不确定是否有办法解决这个问题。Janos谢谢你的更新。这很有帮助。您的问题是显示给定输入的预期输出，因此我们不会猜测。Stack Overflow是一个用于编程和开发问题的网站。这个问题似乎离题了，因为它与编程或开发无关。请参见帮助中心中的。也许或者会是一个更好的提问的地方。也看到
