How to Use the Linux Df Command to Calculate Disk Free Space

If you’re mostly a Windows user or programmer and are porting to linux, you may be thinking that a command that would help you determine the free disk space of your computer would be pretty useful. Luckily, there exists such a tool and is called DF (Display Free disk space).

To get information about the disk space on your system, you can just execute :

df -h

-h stands for Humanly readable, so it’s pretty easy to remember. Upon execution, you get back something like :


Filesystem      Size   Used  Avail Capacity  Mounted on
/dev/disk0s2   113Gi   89Gi   23Gi    80%    /
...

This example is generated on my macintosh pc, so it may defer in your case. As you can see, i have a total of 113GBytes on free space and i’m currently using 89GBytes (hmm, i have to free up some space). This leaves me with 23GBytes on available free disk space and thus i’m using 80% of the hard disk capacity.
