Modified DF

Improved version of the command unix DF.

This was a work for the network course during my master's degree. The objective was to implement an improved version of the command DF. This command analyzes the and inform the user of how much space is used and how much space is free on each of the available disks and volumes. The previous versions of this command generated reports using storage units in megabytes. With the increase of the capacity of the disks it was necessary to update the command to generate report in gigabytes. The source code available below accomplishes this task and it was developed to be executed on the Solaris platform.
