删除iphone垃圾文件的小技巧

iphone用户都应该知道，在是各位使用iphone的同时，也会为手机产生许多不必要的垃圾文件，并且极大的占用你的手机内存，也会使得手机运行变慢，那么我们就必须删掉这些垃圾文件。想用删除这些文件的话，就看看下面的方法吧。

步骤：
1、打开iFunBox,进入SSH终端
2、cd /var/mobile （进入用户目录）
3、du -sm (先看看用户目录共占用了多少空间，返回的是4411，即占用了4G多----这一步可跳过)

4、ls|xargs du -sm（查询每个子目录各占用了多少空间，然后专门挑占用大的进入。就能定位到哪个目录占用的哪个文件占用最多，看看是不是可以删除）
ps:这个命令只能看目录。如果是看当前文件夹的文件大小，请用ls -l即可，第四列是大小，单位字节。
5、在/var/moblie目录 执行find . -size +10000000c|grep .|xargs ls -l命令，查找大于10M的文件(同样第四列是大小)。因为空间占用最厉害的，往往就是这些大文件。挑不需要的删除。

下图是本机的搜索结果。
比如有个23M大小的PDF(见蓝色部分)，分别用goodReader、ifile、必读智慧书各打开过一次，然后再每个目录下都自动缓存了一份。悲催地多被占用了26*3=78M的空间，赶紧删除。


shoui:/User root# find . -size +10000000c|grep .|xargs ls -lr
