简单至极:
URL="http://whatismyip.org/"
curl -s $URL || wget -qO- $URL || lynx -dump $URL || w3m -dump $URL
当然,也有复杂的办法:
w3m -dump http://www.ip138.com/ip2city.asp|awk -F"[" '{print $2}'|awk -F"]" '{print $1}
或者:
w3m -dump http://myip.cn|egrep '[0-9]\.[0-9]+\.[0-9]+\.[0-9]+'|tr -d "您的IP地址: "
w3m -dump http://myip.cn|egrep '[0-9]\.[0-9]+\.[0-9]+\.[0-9]+'|awk '{print $2}'
