1. curl 后面的url必须加双引号，否则访问错误（对特殊的curl）
2. 对于https的地址，找不到证书的话，请使用-k参数来继续测试该地址：
curl -k -v -X GET "https://track.mobcastlead.com/click?offer_id=598&n_id=0&cid=test"
否则收到如下错误：
* error setting certificate verify locations:
CAfile: /etc/pki/tls/certs/ca-bundle.crt
CApath: none
* Curl_http_done: called premature == 0
* Closing connection 0
curl: (77) error setting certificate verify locations:
CAfile: /etc/pki/tls/certs/ca-bundle.crt
CApath: none
3. robocopy 高效复制 ：
robocopy F:\FirstTmp\SoftTmp\Firefox\1203MostLitWorkProfileDel J:\F\Firefox\1203MostLitWorkProfileDel /J /E /R:2 /W:2
4. robocopy 剪切：
robocopy .\ J:\BaiduNetdiskDownload *.VHD /E /J /R:2 /W:2 /MOV
5. in robocopy, /E is better than /S, /J should make it faster, /R means try 2 times
6. win10修改了path后发现，notepad++打开当前文件所在目录并定位到cmd下时，没有继承path,只有管理员运行cmd，会继承path。导致idfa这样的hotstring无法使用。
