Bash终端命令行，使用privoxy将socks代理转成http代理

# Ubuntu/debian
sudo apt-get install privoxy

# Centos
sudo yum install privoxy

# Mac osx
sudo port install privoxy

vi /etc/privoxy/config

#      HTTP parent looks like this:
#
       forward-socks4   /               127.0.0.1:1080  .
#
#      To chain Privoxy and Tor, both running on the same system, you
#      would use something like:
#
       forward-socks5   /               127.0.0.1:1080 .

function proxy_off(){
    unset http_proxy
    unset https_proxy
    unset ftp_proxy
    unset rsync_proxy
    echo -e "已关闭代理"
}

function proxy_on() {
    export no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"
    export http_proxy="http://127.0.0.1:8118"
    export https_proxy=$http_proxy

    export rsync_proxy=$http_proxy
    export HTTP_PROXY=$http_proxy
    export HTTPS_PROXY=$http_proxy
    export FTP_PROXY=$http_proxy
    export RSYNC_PROXY=$http_proxy
    echo -e "已开启代理"
}
