shell操作mongodb,shellmongodb

想通過shell查詢MongoDB的資料

網上好多人說,mongoDB不支援shell,這個說法我是基本贊同的;

但是項目需要,我不得不嘗試著做,關鍵要使用--eval

如我要查詢使用者數量:

#cat count_users.sh

#!/bin/sh

/usr/bin/mongo  xxx --quiet --authenticationDatabase admin -u root -p 'xyz' --eval "db.system.users.count()"

注意:

1.quiet只輸出結果

2.eval這是evaluate javascript

3.--authenticationDatabase admin 執行auth驗證,這個不能忘記啊!

authenticationDatabase可以參看我這篇文章:http://blog.csdn.net/jacson_bai/article/details/41013259
