mongoexport 命令异常方便简单强大！

连接数据库：

jkmiao@jkmiao-ipin:~$ mongo 192.168.1.xx:xxx/jd_58tc_raw

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 

2. 到文件

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

3. 导入

mongoimport -h localhost: -d jd_raw -c jd_58tc_raw --drop ./jd_58tc_output.json
