du - estimate file space usage - 計算文件空間使用情況

Summarize disk usage of the set of FILEs, recursively for directories.
彙總每個文件佔用磁盤空間情況， 遞歸彙總目錄的大小。

Mandatory arguments to long options are mandatory for short options too.
長選項的強制性參數對於短選項也是必需的。

-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)
提高信息的可讀性。

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

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).
