NFS mount System Call in linux

原文转载 http://ramosli.iteye.com/blog/1966202 写的太好了，怕自己忘记，就转载到自己博客。如果有版权问题，请联系我。 在Android开发方面，我是小白，起步没多久。最近用到了sqlite本地缓存数据，我希望像mysql一样通过命令行查看建立的表以及表中的数据，于是用adb shell进入，敲入sqlite3，提示 sqlite3: not found。 网上搜索了一下，网上的文章倒是不少，但如果直接复制人家的命令的话，发现仍然报错，于是自己研究了下，总结如下，希望遇到同样问题的朋友少走弯路： 需要获取手机的root权限，方法很多了，我用的是360一键Root，有时也用百度一键Root 从其他手机拷贝sqlite3文件到PC，我是从模拟器copy出来的，为方便大家，附件就有，可以直接下载哈 进入手机建立个临时目录 开始—cmd—adb shell—mkdir /mnt/sdcard/tmp，然后退出到cmd下 adb push D:/temp/sqlite3 /mnt/sdcard/tmp copy文件到/system/xbin adb shell su (这一步报permission denied的话是Root没有成功，重新Root吧) cp /mnt/sdcard/tmp/sqlite3 /system/xbin/sqlite3 (注意
