Project Description Project Description

Create a $C++{17}^1$ console ${?}^2$ application that shows disk usage $($based on the UNIX command$).$ du $($abbreviated from disk usage$)$ is inspired by a standard Unix program used to estimate file space usage on a file system. Your application will parse files from a given directory on a hard drive.

Purpose:

To display allocation space $($not absolute file space$)$ for each file and directory contained in a given pathname

Usage:

du takes at least a single argument, specifying a pathname

If no pathname is provided, the current directory is used du reports:

Pathnames and the sum of the clusters allocated for each directory

The sum of clusters for the given root directory

Switches:

Switches provide input options for additional functionality

$"-"$ is used before a single letter switch or a collection of single letter switches

$"--"$ is used before a word switch

Program Interfaces

du $[-$skhznrb$][--$he$1$p$][--$version$][--$b$7$ock$-$size$=$dddd$][$folder$]*$

Otherwise, the specified folder is$],[$where the scan begins.$]]]]$

Input Rules:

Cannot use $-$b and $-$h switches together

$-$k and $-$block$-$size are incompatible

$-z$ and $-n$ switches are incompatible

No switch may be duplicated

There cannot be unknown switches
