This Is Beginning Class Windows Powershell 20 Programmingi Have Two

This is beginning class, Windows Powershell 2.0 Programming. I have two assignments that I need yesterday but will be happy to have 1 or both by Tuesday or whatever is humanly possible. Will pay a little more to get these two caught up. Just need very simple script that will be uploaded using Word to an online class. Anybody interested?

Willing to pay $20+- per task to get caught up. TASK 1: Using the Get-Process and Where-Object cmdlets, write a script that displays the Processes with an Id of less than 1000. •Using the Get-ChildItem and Where-Object cmdlets, write a script that displays the files in C:\Windows with an Attribute equal to Archive TASK 2: •Write a script that implements a Math quiz — •Ask 5 questions — •Check the answers using an if or switch statement •Display the score at the end Let me know and I'll be waiting with any more info you need. klynn

Paper For Above instruction

Throughout the evolution of Windows PowerShell, scripting has become an indispensable skill for IT professionals, system administrators, and even hobbyists who seek automation, system management, and data analysis. This paper addresses two fundamental scripting exercises in PowerShell 2.0, designed to improve understanding of process management, file system interaction, and scripting logic through practical implementation of cmdlets and control flow statements.

Introduction

PowerShell 2.0, released in 2009, marked a significant milestone by introducing a robust, object-oriented scripting environment that enhanced automation capabilities. Mastery of essential cmdlets like Get-Process, Get-ChildItem, and control structures such as if and switch forms the backbone of a proficient PowerShell scriptwriter. The two tasks discussed here encapsulate core concepts—process filtering by ID, file attribute filtering, and simple user interaction through a math quiz—serving as practical exercises that foster foundational scripting skills.

Task 1: Filtering Processes with Get-Process and Where-Object

The first task involves retrieving and filtering system processes based on their process IDs. Using the Get-Process cmdlet, which fetches all running processes, and piping the output to Where-Object for filtering, a script can efficiently display processes with IDs less than 1000. The script exemplifies the use of pipeline operations and conditional filtering, crucial skills in PowerShell scripting.

Sample script:

Get-Process | Where-Object { $_.Id -lt 1000 }

This command retrieves all processes and outputs only those where the process ID ($_ representing each object in the pipeline) is less than 1000. The result includes process names, IDs, and other properties, providing insight into lightweight processes or system-internal processes typically with lower IDs.

Task 2: Filtering Files by Attribute within a Directory

The second task requires listing files in the C:\Windows directory with the Archive attribute set. Utilizing Get-ChildItem, which enumerates files and folders, combined with Where-Object to filter by the Archive attribute, demonstrates effective file system querying.

Sample script:

Get-ChildItem -Path C:\Windows | Where-Object { $_.Attributes -band [IO.FileAttributes]::Archive }

This script uses bitwise AND (&band) to check if the Archive attribute is set for each file. Files matching the criteria are displayed, allowing users to identify files flagged for archival or backup purposes. Understanding file attributes is vital for managing data and system configurations.

Task 3: Creating an Interactive Math Quiz Script

The third task is to create an interactive PowerShell script that administers a math quiz by posing five questions, evaluating the provided answers, and displaying the final score. This exercise emphasizes the use of variables to track scores, Read-Host for user input, and control flow structures such as if and switch for answer validation.

Sample script:

# Initialize score

$score = 0


Question 1


$answer1 = Read-Host "What is 2 + 2?"


if ($answer1 -eq '4') {


$score++


}


Question 2


$answer2 = Read-Host "What is 5 * 3?"


if ($answer2 -eq '15') {


$score++


}


Question 3


$answer3 = Read-Host "What is 10 / 2?"


if ($answer3 -eq '5') {


$score++


}


Question 4


$answer4 = Read-Host "What is 7 - 3?"


if ($answer4 -eq '4') {


$score++


}


Question 5


$answer5 = Read-Host "What is 9 + 6?"


if ($answer5 -eq '15') {


$score++


}


Display final score


Write-Output "Your total score is $score out of 5."

This script demonstrates basic user input, conditional logic, and output in PowerShell, providing a simple yet effective educational tool.

Conclusion

These exercises exemplify core PowerShell scripting techniques, fostering skills necessary for automation, data filtering, and user interaction. Mastery of these tasks offers a foundation for more complex scripting endeavors, such as automation workflows, system monitoring, and custom tools for administrative tasks. As PowerShell continues to evolve, understanding these basic concepts remains essential for leveraging its full potential in modern IT environments.
