Unix / Linux: See Colourised Filesystem Disk Space Usage

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.

How do I use pydf?

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

To see filesystems having 0 blocks, enter:
$ pydf -a
Sample outputs:
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
