The df command is used to display the disk file usage. It shows a
summary of the amount of space used and available on the system.
When run with no arguments it reports information about every
``filesystem''
Example:
Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda4 120576100 73252260 41198892 65% / tmpfs 4092144 656 4091488 1% /dev/shm /dev/sda2 198337 69000 119097 37% /boot
However, if you want to break down to only the relevant information, like
how much space is available in my home directory or in /tmp, you can use those
directories as an argument.
Example:
[jdpoisso@umms-amino ~]$ df ~
Filesystem 1K-blocks Used Available Use% Mounted on
10.2.1.18:/export/umms-amino/home/jdpoisso
11134798720 9499291008 1635507712 86% /home/jdpoisso
[jdpoisso@umms-amino ~]$ df /tmp
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/cciss/c0d0p2 39674224 5665648 31960692 16% /
[jdpoisso@umms-amino ~]$
If you find the numbers a bit confusing, try using the
``-h'' argument. K stands for
kilobytes, M megabytes, G for gigabytes, and T
for terabytes.
Example:
[jdpoisso@umms-amino ~]$ df -h ~ Filesystem Size Used Avail Use% Mounted on 10.2.1.18:/export/umms-amino/home/jdpoisso 11T 8.9T 1.6T 86% /home/jdpoisso
