Discus – Show Colourised Disk Space Usage in Linux

In our last article, we have explained how to use df (disk filesystem) utility to report file system disk space usage in Linux. We have discovered yet a another great utility for the same purpose but with a prettier output, called discus.

Discus is a df-like, highly configurable utility for checking disk space utilization in Linux, intended to make df prettier with fancy features such as colored output, bar graphs, and smart formatting of numbers. To configure it, you may copy its main configuration file /etc/discusrc to ~/.discusrc and do your customization in there.

  1. Hey guys I can’t install it on Fedora:

    $ sudo yum provides discus
    Last metadata expiration check: 0:00:20 ago on Di 02 Okt 2018 10:54:21 CEST.
    Error: No Matches found

    Can you guys help me?

  2. Wow, I had no idea anyone still used this. I wrote Discus in 2000. I haven’t thought about it in years, yet here is a brand-new review of it.


  3. This package is not available in CentOS 7 or EPEL repositories. Tecmint, why do you hurt me so? This is the second thing I have tried from this site this month that does not work on CentOS. Recommend testing before writing.
