 Here's the most basic example of Linux df command, with output shown here from a CentOS Linux computer:

[root@hc]# df

The -h option stands for "human readable", so as you can see, my current Linux system has one filesystem, and it is mounted as / (the root filesystem), and it is a 10GB filesystem, with 5.5GB used, 4.6GB available, and it is 55% used (which is pretty easy to see with round numbers like this example).
