Harddisk Usage

Information about disk usage

df -h

The result of the df command is:

Filesystem            Size  Used Avail Use% Mounted on
/dev/md2              375G   41G  315G  12% /
tmpfs                 2.0G     0  2.0G   0% /lib/init/rw
udev                   10M   52K   10M   1% /dev
tmpfs                 2.0G     0  2.0G   0% /dev/shm
/dev/md1              510M   37M  448M   8% /boot

Partition Layout

And the partitions:

fdisk -l

This command shows you the partition layout.

Disk /dev/sda: 85.8 GB, 85899345920 bytes
255 heads, 63 sectors/track, 10443 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000d6430

Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1       10255    82373256   83  Linux
/dev/sda2           10256       10443     1510110    5  Extended
