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.

How to Use pydf Command in Linux
If you run only the “pydf” command without specifying an argument, it will display just information on disk space usage along with all mounted file systems.
To check which file system has 0 blocks, simply run the following command along with the “
-a” or “
# pydf -a
To see the output in human-readable format, use the option “
-h", which will print sizes (e.g., 10K, 10M, 10G).
# pydf -h
To print sizes in kilobytes (e.g., 1024 block size) use the option “
-k” as shown below.
# pydf -k
To print summary output in megabytes (e.g., 1048576 block size) use option “
-m” as shown below.
# pydf -m
To print sizes in gigabytes (e.g., 1073741824), specify the option “
-g” as shown below.
# pydf -g
To see the information about inodes instead of blocks, use the argument “
-i” as given below.
