Ubuntu command line check disk usage

To check hard disk usage on Ubuntu from a terminal (command line), issue the following command  in your terminal.

liping:~$ df -h

-h stands for human which makes it readable by us humans, otherwise the file size will be in bytes:)

After you issue the command, you would  see your disk usage similar to the info given below.

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda7              68G   23G   43G  35% /
udev                   10M     0   10M   0% /dev
