## Further comments
The default size of mac `df` is 512blocks, and the default size of linux is
1024 bloks. Therefore, when executing the command, use `df -k` to limit the
output unit to 1024blocks.
The output results of mac os and Linux os are also different, so the
corresponding information is obtained according to different systems.
