Fdisk also has a view project, which focuses on information about partition tables and also serves disk partitions, while df focuses on displaying information about all file systems in the current system

1. Df lists the overall disk usage of the file system

Because almost all the data read by df is for an entire file system, so the scope of reading is mainly information in Superblock, so this command displays the results very quickly!

Supplement: easy-to-read capacity formats, such as K, M, G
