我正在尝试从ifconfig中获取以下格式化输出:
en0: 10.52.30.105
en1: 10.52.164.63
我已经能够通过以下命令至少弄清楚如何获取IP地址(除去localhost),但这还不足以满足我的要求:
ifconfig | grep -E 'inet.[0-9]' | grep -v '127.0.0.1' | awk '{ print $2}'
谢谢!

这适用于FreeBSD,它是苹果的核心: - )
#!/bin/sh
for i in $(ifconfig -l); do
case $i in
(lo0)
;;
(*)
set -- $(ifconfig $i | grep "inet [1-9]")
if test $# -gt 1; then
echo $i: $2
fi
esac
done

在Debian / RHEL系统上,您可以执行以下操作---
#!/bin/sh
echo "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"
echo "Interface: IP : MASK : BROADCAST : HWADDR"
echo "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"
for i in $(ifconfig -a| grep -v ^$| grep ^[a-z*] | awk '{print $1}')
do
case $i in
(lo)
;;
(*)
ip=`(/sbin/ifconfig $i | awk /'inet addr/ {print $2}' | cut -f2 -d":" )`
bcast=`(/sbin/ifconfig $i | awk /'Bcast/ {print $3}' | cut -f2 -d":" )`
mask=`(/sbin/ifconfig $i | awk /'inet addr/ {print $4}' | cut -f2 -d":" )`
hwaddr=`(/sbin/ifconfig $i | awk /'HWaddr/ {print $4,$5}' | cut -f2 -d" " )`
if [ -z $ip ]; then
ip="NA"
fi
if [ -z $bcast ]; then
bcast="NA"
fi
if [ -z $mask ]; then
mask="NA"
fi
if [ -z $hwaddr ]; then
hwaddr="NA"
fi
echo $i: $ip : $mask : $bcast : $hwaddr
;;
esac
done
