Difference between `du` and `df`
`du` (Disk Usage) measures the space occupied by specific files or directories on a disk. In contrast, `df` (Disk Free) shows the available space of the entire file system. `du` focuses on aggregating usage within the file system, while `df` focuses on the total capacity and free space of a mounted volume. Therefore, the results of the two reports may differ.
