#1:必须安装CURL
#opkg --force-depends --force-overwrite install /tmp/libmbedtls_2.14.1-1_arm_cortex-a9.ipk
#opkg --force-depends --force-overwrite install /tmp/ca-bundle_20180409_all.ipk
#opkg --force-depends --force-overwrite install /tmp/libcurl_7.60.0-3_arm_cortex-a9.ipk
#opkg --force-depends --force-overwrite install /tmp/curl_7.60.0-3_arm_cortex-a9.ipk
#或者安装支持HTTPS的完整WGET
#2:拷贝ddnspod.sh和ddnspod.conf到相应的目录,并设置权限为777
#3:在/etc/ppp/ip-up.d目录新建一个文件autoddns.sh，权限0755，内容如下：
#/bin/sh
sh /etc/config/ddnspod.sh >> /tmp/log/dnspod.log 2>&1 &
#只要wan口发生变化，就会执行脚本去DNSpod更新A记录的IP。
#简单测试一下：/etc/init.d/network restart

Try to make the execution environment as predictable as possible:
All commands below are invoked via command, so we must make sure that command
itself is not redefined as an alias or shell function.
(Note that command is too inconsistent across shells, so we don't use it.)
command is a builtin in bash, dash, ksh, zsh, and some platforms do not even have
an external utility version of it (e.g, Ubuntu).
command bypasses aliases and shell functions and also finds builtins
in bash, dash, and ksh. In zsh, option POSIX_BUILTINS must be turned on for that
to happen.

Output the ultimate target's canonical path.
Note that we manually resolve paths ending in /. and /.. to make sure we have a normalized path.
