Pydf – An Alternative “df” Command to Check Disk Usage in Different Colours

The “pydf” (Python Disk File System) is an advanced command line tool and a good alternative to the “df command”, which is used to display the amount of used and available disk space on a mounted filesystem, the same as df command, but in different colors. The output of the pydf command can be customizable according to your needs.

This “pydf” command is written in python language that displays the amount of disk usage and available space on Linux mounted file system, using custom colors for different file system types.

  1. Nice idea but you seem to have forgotten two specifics. Linux is NOT one or two particular distros and not all distros have the same things in their repositories. It would therefore be nice if you included the location of the sources or some way of manually installing it onto something other than a Red Hat or Ubuntu templated system.
