CS632P Project 1 - Scanning OS files with argparse and logging

In this assignment you will need to use Python’s argparse and logging modules. Device a Python app that will read the contents of any computer, and it should produce an output based on the input provided. The output will be written into a logging/logger log file, for a view on demand and verification. All the lines of the log file should be accompanied by time stamps, along with level message.

The ’main’ Python script (list_content.py) should expect certain positional and non-positional arguments. It should include a ‘help’ switch ‘-h’ which will provide all possible switches and arguments. It should also include a ‘mutually exclusive group’ for ‘-v’ (verbose) or ‘-q’ (quiet) mode.

The additional allowed switches/arguments to the script (list_content.py) should be:

1. ‘-d’: To list all the drives of the machine with the following info:
   • Drive name / letter
   • Total number of directories
   • Total number of files
   • Total allocated, used, free storage
   • A positional argument ‘drv’ that will indicate the name of a single drive to report the above info.
2. ‘l’: To list all the folders in a given drive with the following info:
   • Folder name
   • Total number of files per folder
   • Total storage used per folder and sum of all storage for all folders.
   • A positional argument ‘fld’ that will pass the folder name to report the above info.
3. ‘-f’: To list all the files of the machine with the following info:
   • File name
   • File type (‘py’, ‘ipynb’, ‘exe’, ‘txt’, ‘csv’, ‘pdf’, ‘other’)
   • File size
   • Date/Time stamp of the file
   • A positional argument ‘fil’ that will pass the file name to report the above info.
4. ‘-t’: To list all the types of files exist in the machine with the following info:
   • File type
   • Total number of files per file type
   • Total storage used per file type
   • A positional argument ‘typ’ that will indicate the type of file to report the above info.

You should choose the various logging levels appropriately.

• When listing info about folders and files the level should be INFO.
• When the passing value for folder or file is not valid (folder or file doesn’t exist) the level should be WARNING.
• Any computation errors should be captured (e.g. total storage of files, folders, drives cannot be negative) and classified under the ERROR level.
• When Python can NOT read the OS structure, the level should be CRITICAL.
• Any other activity/message of the logger should have a level of DEBUG.
