duf is one of the fancy Linux disk monitoring utilities written in Golang. It is released under MIT license and It supports Linux, macOS, BSD, and even Windows too. Some of the core features of duf include:
- a better ‘df command‘ alternative.
- Light and Dark color scheme.
- Output in JSON format.
- Option to sort, group, and filter output.
- Adjustable terminal Height and Width.
There are two ways you can install DUF. You can either build it from the source or download the setup in native format (.rpm or .deb) specific to Linux distribution and install it. I will walk you through both methods.
Building Duf from SourceYou need to set up the Go (1.12 or above) environment to compile duf. If you don’t have Go set up in your machine, take a look at our comprehensive article on how to set up Go in Ubuntu.
$ git clone https://github.com/muesli/duf.git $ cd duf $ go buildInstalling Duf from Packages
You can download the duf package from the Github repo directly or use the wget command.
--------- On Debina, Ubuntu & Mint --------- $ wget https://github.com/muesli/duf/releases/download/v0.6.0/duf_0.6.0_linux_amd64.deb $ dpkg -i duf_0.6.0_linux_amd64.deb --------- On RHEL, CentOS & Fedora --------- $ wget https://github.com/muesli/duf/releases/download/v0.6.0/duf_0.6.0_linux_amd64.rpm $ rpm -ivh duf_0.6.0_linux_amd64.rpmUsage of Duf (Disk Usage) Tool in Linux
Now, launch the application by simply typing duf from the terminal.
$ dufLinux Disk Usage
Duf has a lot of features, so a good place to start would be to use --help
option.
$ duf --helpDuf Help
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/logCheck Disk Usage of Partitions
You can pass --all
flag to display Pseudo, inaccessible, and duplicate file systems.
$ duf -allDuf Options
Instead of printing block usage, we can print Inode usage bypassing --inodes
as an argument.
$ duf --inodesCheck Linux Inode Usage
You can sort output or display only certain columns based on certain keywords.
$ duf --sort size
You have the option to print only certain columns bypassing the column name as an argument to --output
flag.
$ duf --output used,size,avail,usageLinux Disk Usage Summary
Below are the list of valid keywords.
- mountpoint
- size
- used
- avail
- usage

Duf comes with a light and dark color scheme. To set the color scheme, use the following commands.
