要获取每个appid的次数

grep '"appid\\\\\\":\\\\\\"[^"]*' -o text.log| sort | uniq -c | sort -rn

结果如下：

   2313 "appid\\\":\\\"RC528E2DD8E745E195173D9F8BE48436\\\
   1855 "appid\\\":\\\"R165ECD08C90491B89C809753D1F322F\\\
   1841 "appid\\\":\\\"R40913E89BFF4C79A210418E6E5BE663\\\
    478 "appid\\\":\\\"R9EDC9514BED480BA97E0C3BEC7A7828\\\
    423 "appid\\\":\\\"R7C638312DA94C54BFE5B3BE2FE33E44\\\

感谢老神医！
