20.3. Filesystems

The df command reports the system’s disk space usage. If you type the command df at a

shell prompt, the output looks similar to the following:

Filesystem 1k-blocks Used Available Use% Mounted on

/dev/hda2 10325716 2902060 6899140 30% /

/dev/hda1 15554 8656 6095 59% /boot

/dev/hda3 20722644 2664256 17005732 14% /home

By default, this utility shows the partition size in 1 kilobyte blocks and the amount of used

and available disk space in kilobytes. To view the information in megabytes and gigabytes,

use the command df -h. The -h argument stands for human-readable format. The output

looks similar to the following:

Filesystem Size Used Avail Use% Mounted on

/dev/hda2 9.8G 2.8G 6.5G 30% /

/dev/hda1 15M 8.5M 5.9M 59% /boot

/dev/hda3 20G 2.6G 16G 14% /home

To view the system’s disk space usage in a graphical format, use the Filesystems tab in the

GNOME System Monitor. To start it on the GNOME desktop, go to the Main Menu Button

(on the Panel) => Programs => System => System Monitor or type gtop at a shell prompt

from within any X Window System desktop. Then choose the Filesystems tab.

The du command displays the estimated amount of space being used by ﬁles in a directory. If

you type du at a shell prompt, the disk usage for each of the subdirectories will be displayed

in a list. The grand total for the current directory and subdirectories will also be shown, as

1 2 ... 169 170 171 172 173 174 175 176 177 178 179 ... 267 268
