Common commands for Linux file systems

01. Statistical File System occupancy = DF [option] [user name]

-H: Display capacity

-A: Show all file system Information

-T: Show file system type

-M: Display capacity in megabytes

-K: Display capacity in kilobytes

02. Statistics directory or file size = du [option] [directory or filename]

-A: Show each sub-file size

-H: Display size units

-sh: Total usage of statistics

DF and du differences:

DF: Not only to consider the size of the file, but also to consider the amount of space occupied by the command or program (the most common is that the file has been deleted, but the program is not free space)

Du: Only consider file and directory size
