#  du - estimate file space usage - 计算文件空间使用情况 #

Summarize disk usage of the set of FILEs, recursively for directories.  
汇总每个文件占用磁盘空间情况， 递归汇总目录的大小。

Mandatory arguments to long options are mandatory for short options too.  
长选项的强制性参数对于短选项也是必需的。

`-d, --max-depth=N`  
print the total for a directory (or file, with `--all`) only if it is `N` or fewer levels below the command line argument; `--max-depth=0` is the same as `--summarize`.

`-h, --human-readable`  
print sizes in human readable format (e.g., 1K 234M 2G)  
提高信息的可读性。

`-l, --count-links`  
count sizes many times if hard linked

display only a total for each argument  
仅显示总计，当前文件夹的大小。

The SIZE argument is an integer and optional unit (example: 10K is 10\*1024). **Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,… (powers of 1000).**
