linux下：
ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}'
先获取含有IP的行，再去掉含有127.0.0.1的行。最后获取IP所在的列

esac
echo "$IP"
vi ip.sh
#!/bin/bash
ifconfig $1|sed -n 2p|awk '{ print $2 }'|awk -F : '{ print $2 }'
##ifconfig $1|sed -n 2p|awk '{ print $2 }'|tr -d 'addr:'#这个也可以实现####
执行：
./ip.sh eth0
