Unix/Linux : How to find out the hard disk size?


Tags : hard-disk-size filesystem unix linux df-h diskspace

It is easy to find out the available or used up hard disk space in a Graphical User Interface environment such as MacOSX or KDE. However, it is not so easy to find out the available or used up hard disk space in terminal or command line. Since I work mostly with ssh shell and vi, I need to find out the hard disk usage information with command line application.

How to find out the used and available hard disk size in Unix/Linux OS terminal?

Use the df -h command.

df -f

Sample output :

 guest@porteus:~$ df -h
 Filesystem Size  Used Avail Use% Mounted on
 aufs 2.3G  205M  2.1G 9% /
 devtmpfs 1.9G 20M  1.9G 1% /dev
 /dev/sda1 100M 25M 76M  25% /mnt/sda1
 /dev/sda2 298G 43G  256G  15% /mnt/sda2
 /dev/sdb1 7.3G  1.7G  5.7G  23% /mnt/sdb1
 /mnt/live/run 1.9G  176M  1.8G  10% /run
