linux grep 取出特定字符串并统计个数

原始日志如下：

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\
    384 "appid\":\"com.xxx.homebase\

感谢老神医！
