The Df command is used to view the file system by disk partition. You can add parameters to view the remaining disk space. The command format is as follows:

Df-hl

Display format:

File System capacity used available % mount point

/Dev/hda5487M120M342M27 %/

/Dev/hda1981M21M911M3 %/boot

None125M0125M0 %/dev/shm

/Dev/hda229G4.9G23G18 %/home

/Dev/hda320G4.8G14G27 %/usr

/Dev/hda724G510M22G3 %/var

/Dev/hdb275g751_100 %/

/Dev/hdb275g751_100 %/, as shown in the following example:

HD hard disk interface second hard disk B), second partition 2), capacity is 75G, 75G used, available is 0, so the utilization is 100%, mounted to the root partition directory /)
