What is mounting?

Mounting is a very important function. It attaches a device (usually a storage device, which can mount optical disks, hard disks, tapes, optical disk image files, etc.) to an existing directory. (This directory does not need to be empty, but the previous contents in this directory will not be available after mounting).

The Linux operating system treats all devices as files. It integrates the resources of the entire computer into a large file directory. If we want to access the files in storage, we must mount the partition where the files are located. An existing directory, and then access the storage device by accessing this directory. Mounting requires a mount source and mount point.

Mount source: the object to be mounted

Mount point: a specific directory

-B. --block-size specifies the unit size, such as 1K, 1M, etc.

-h, --human-readable displays

-H in human-readable formats such as GB, MB, KB, etc. --si and -h parameters are the same, but not 1024, but 1000, that is, 1K=1000, not 1K=1024

-i, --inodes, not the hard disk capacity, but the inode number

-k is displayed in quantity, and each file system is displayed in KB capacity, which is equivalent to --block-size=1k

-m, and each file system is displayed in MB capacity, which is equivalent to --block-size=1m

-l, --local, only display the local file system

--no-sync; Do not call the sync command before counting usage information

-sync, call the snyc command before counting usage information

-P, portability, use POSIX format to display
