批量代理测试

到 http://www.cnproxy.com/proxyedu1.html等网站把代理列表放到 ip.txt 里，要保证ip在行首，或者用默认的http://proxy.ipcn.org/proxylist.html代理列表。

#!/bin/bash
if [ -e ip.txt ];then
    echo "use ip.txt";
else
    w3m -no-proxy -dump http://proxy.ipcn.org/proxylist.html > ip.txt
fi

arg=$1
if [ $# -eq 0 ]; then
    arg="p"
fi

testurl="http://www.google.com/index.html"
if [ $arg = 's' ]; then
    testurl="https://www.dropbox.com/"
fi

iplist=`cat ip.txt|sed -e "s/[ \t].*//g" -e "/^$/d"`
for i in $iplist
do
    if [ $arg = 's' ]; then
        a=`curl --proxy $i --connect-timeout 3 $testurl 2>/dev/null |grep dropbox`
    else
        a=`curl --proxy $i --connect-timeout 3 $testurl 2>/dev/null |grep google`
    fi

    if [ "$a" != "" ]
    then
        echo $i
    fi
done
用s作参数获得支持https的代理。因为用了3 秒超时，速度有点慢，好像还不能正常终止。
试一下，得到以下可用代理：
