You can print only specific file systems or devices by passing it as an argument. Since I created this machine in a single partition everything is mounted on the root (/). Based upon your partition scheme you will see different output.
$ duf /home /usr /opt $ duf /root/ $ duf /var/log
Another example would be sorting the output based on the size in a particular order, here’s what you need to type:
duf --sort size
And, the output should look like:
You can pass --all flag to display Pseudo, inaccessible, and duplicate file systems.
$ duf -all
You have the option to print only certain columns bypassing the column name as an argument to --output flag. Example:
$ duf --output used,size,avail,usage
