Command to view hard disk size

The df -hdf command can get information about how much space is being used on the hard disk, how much space is left, etc. It can also show how all file systems are using i nodes and disk blocks.

Df command is linux system to disk partition as a unit to view the file system, you can add parameters to view the remaining disk space information, command format: df -hl

Display format is:

File System Capacity Used Available % Mount Points Used

Filesystem Size Used Avail Use% Mounted on

/dev/hda2 45G 19G 24G 44% /

/dev/hda1 494M 19M 450M 4% /boot

/dev/hda6 4.9G 2.2G 2.5G 47% /home

/dev/hda5 9.7G 2.9G 6.4G 31% /opt

none 1009M 0 1009M 0% /dev/shm

/dev/hda3 9.7G 7.2G 2.1G 78% /usr/local

/dev/hdb2 75G 75G 0 100% /

/dev/hdb2 75G 75G 0 100% /

The second hard disk (b) of the HD hard disk interface, the second partition (2), the capacity is 75 GB, the use of 75 GB, the availability is 0, so the utilization rate is 100%, mounted to the root partition directory (/).
