1.通过awk获取IP地址[[email protected] ~]# ifconfig eth2 | grep inet                    inet addr:10.3.151.25  Bcast:10.3.151.255  Mask:255.255.255.0                    inet6 addr: fe80::250:56ff:fe80:6e7e/64 Scope:Link[[email protected] ~]# ifconfig eth2 | grep "\binet\b"                    inet addr:10.3.151.25  Bcast:10.3.151.255  Mask:255.255.255.0[[email protected] ~]# ifconfig eth2 | grep "\binet\b" | awk ‘{print $0}‘                    inet addr:10.3.151.25  Bcast:10.3.151.255  Mask:255.255.255.0[[email protected] ~]# ifconfig eth2 | grep "\binet\b" | awk ‘{print $2}‘addr:10.3.151.25[[email protected] ~]# ifconfig eth2 | grep "\binet\b" | awk ‘{print $2}‘| awk -F ‘:‘ ‘{print $2}‘10.3.151.25
