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/HDB2 75G 75G 0 100%/

/DEV/HDB2 75G 75G 0 100%/

With the above output as an example, the meaning of the expression is:

The second hard drive interface (b), the second partition (2), the capacity is 75G, with 75G, usable is 0, so the utilization is 100%, is mounted to the root partition directory (/).
