问题描述
我正在寻找一个命令行解决方案,它会返回本地主机的主(第一)IP地址,而不是127.0.0.1
I am looking for a command line solution that would return me the primary (first) IP address of the localhost, other than 127.0.0.1
解决方案应该有效至少对于Linux(Debian和RedHat)和OS X 10.7 +
The solution should work at least for Linux (Debian and RedHat) and OS X 10.7+
我知道 ifconfig
可用于但这些平台之间的输出并不一致。
I am aware that ifconfig
is available on both but its output is not so consistent between these platforms.
推荐答案
使用 grep
从过滤IP地址ifconfig
:
ifconfig | grep -Eo'inet(addr :)?([0-9] * \。){3} [0-9] *'| grep -Eo'([0-9] * \。){3} [0-9] *'| grep -v'127.0.0.1'
或者 sed
:
ifconfig | sed -En的/ 127.0.0.1 //; s /.* inet(addr :)?(([0-9] * \。){3} [0-9] *)。* / \\\ / p'
如果您只对某些接口,wlan0,eth0等感兴趣,那么:
If you are only interested in certain interfaces, wlan0, eth0, etc. then:
ifconfig wlan0 | ...
您可以将 .bashrc
中的命令别名改为创建你自己的命令,例如 myip
。
You can alias the command in your .bashrc
to create your own command called myip
for instance.
alias myip =ifconfig | sed -En的/ 127.0.0.1 //; s /.* inet(addr :)?(([0-9] * \。){3} [0-9] *)。* / \2 / p'
更简单的方法是 hostname -I
(主机名-i
旧版本主机名
但请参阅注释)。但是,这仅适用于Linux。
A much simpler way is hostname -I
(hostname -i
for older versions of hostname
but see comments). However, this is on Linux only.
