mongoexport 命令异常方便简单强大！

连接数据库：

1.  导出10条数据到标准输出

 mongoexport -h 192.168.1.xx:xxxxx -d jd_58tc_raw -c jd_raw_38 -f 'jdJob' -q '{"jdJob.age":/25岁/}' --limit 10

2. 到文件

$ mongoexport -h 192.168.1.97:27027 -d jd_58tc_raw -c jd_raw_38 -f 'jdJob' -q '{"jdJob.age":/25岁/}' --limit 10 --pretty -o jd_58tc_output.json
