Unix / Linux: See Colourised Filesystem Disk Space Usage

Posted on in Categories Linux last updated June 19, 2012

The pydf command displays the amount of used and available space on your file systems, just like df command, but in colors. The output format is completely customizable.

This is a little known tool (python script) that displays the amount of disk space available on the mounted filesystems, using different colours for different types of filesystems.

Install pydf

Use the apt-get command to install pydf under Debian / Ubuntu Linux:
$ sudo apt-get install pydf

FreeBSD user can use the port as follows:
# cd /usr/ports/sysutils/pydf/ && make install clean
Or, add the package using the pkg_add command:
# pkg_add -r pydf

How do I use pydf?

Simply type the command as follows:
$ pydf
Sample outputs:

pydf command
Fig.01: pydf command in action

To see filesystems having 0 blocks, enter:
$ pydf -a
Sample outputs:
pydf command
Fig.02: See all file systems with 0 blocks

To see human readable output i.e. show sizes in human readable format (e.g., 133K 2341M 2448G), enter:
$ pydf -h
The following option is same as -h, but use powers of 1000 not 1024:
$ pydf -H
To see information about inodes instead of blocks, enter:
$ pydf -i
Disable colourised output i.e. do not use colours:
$ pydf --bw
See quick demon of pydf command:

How do I customize pydf command colors?

Edit a file called /etc/pydfrc which is act as system wide main configuration file:
# vi /etc/pydfrc
You can use per-user configuration file ~/.pydfrc:
$ cp /etc/pydfrc ~/.pydfrc
$ vi ~/.pydfrc

  2. Nic little tool, thanks.
    Is there also something like “pydu” or “kdirstat” for comand line?

  3. I dislike the so-called “human-readable” format (it’s really “lossy abbreviation”), and pydf has nothing else. The best way of presenting large numbers is with thousands separators. That way the numbers themselves provide a graphic representation of their relative sizes while still being human readable. I wrote this wrapper for df:
    http://cfajohnson.com/shell/scripts/dfc-sh

  4. Tried installing pydf on FreeBSD 9 and found I had to alter the shebang line of the python script to get it to work properly. The script (/usr/local/bin/pydf) installs with

    #!/usr/bin/python

    and this needs to be changed to:

    #!/usr/local/bin/python

    Works well once adjusted.

  5. Very recently, I wrote a tool in C that displays space usage using graphs and colors. It has also other capabilities such as html and TeX export of the data. Have a look at the wiki page for some screenshots and information.
    Works on Linux, *BSD and OSX and is already in FreeBSD and OpenBSD ports and packaged in some Linux distro as well (Mageia, Debian, Gentoo,…).
    You might want to give it a go. 😉

  6. On CentOS 7, after running sudo yum install epel-release, I still couldn’t install pydf by running sudo yum install pydf. However I was able to install through pip by running:
    yum install -y python-pip
    sudo pip install pydf
