*Task:* Automatically move all “log” files older than 30 days from the “Logs” folder to the “OldLogs” folder.
To achieve this, you can use the following code snippet:
“`powershell
$source = “C:Logs”
$destination = “C:OldLogs”
$thresholdDate = (Get-Date).AddDays(-30)
Get-ChildItem -Path $source -Recurse -File -Filter “*.log” | Where-Object { $_.LastWriteTime -lt $thresholdDate } | Move-Item -Destination $destination
“`
This script identifies and moves the specified files while maintaining their directory structure, streamlining your ongoing file management needs.
2. Simplifying User Management in Active Directory
For IT administrators, user management is critical to maintaining access controls and ensuring optimal system performance. Through automation with PowerShell examples, you can easily manage user accounts in Active Directory with efficiency and precision.
*Task:* Identify all users in the “Sales” organizational unit (OU) that have not logged in for 60 days and disable their accounts.
“`powershell
$ouPath = “OU=Sales,DC=yourdomain,DC=com”
$thresholdDate = (Get-Date).AddDays(-60)
Import-Module ActiveDirectory
Get-ADUser -Filter * -SearchBase $ouPath -Properties LastLogonTimestamp | Where-Object { $_.LastLogonTimestamp -lt $thresholdDate } | Disable-ADAccount
“`
The above script demonstrates how PowerShell can simplify user management tasks, ensuring your organization’s security and productivity.
3. Automating Software Installation
Installing software on multiple machines can be a tedious process. PowerShell enables you to automate this task, significantly reducing the time spent on repetitive installations.

$localPath = “C:Tempchrome_installer.exe”
Invoke-WebRequest -Uri $installerUrl -OutFile $localPath
Invoke-Command -ComputerName $remoteComputer -ScriptBlock { Start-Process -FilePath “C:Tempchrome_installer.exe” -ArgumentList “/silent /install” -Wait }
“`
This example illustrates the power of automation with PowerShell in streamlining software deployments across an organization.
4. Scheduling Automated Tasks
PowerShell allows you to automate tasks and run them on a specified schedule. Instead of manually executing scripts, you can use the built-in Task Scheduler to streamline your workflow further.
*Task:* Schedule a PowerShell script to run daily at 2:00 PM.
“`powershell
$scriptPath = “C:ScriptsYourScript.ps1”
$action = New-ScheduledTaskAction -Execute ‘powershell.exe’ -Argument “-NoProfile -ExecutionPolicy Bypass -File $scriptPath”
$trigger = New-ScheduledTaskTrigger -Daily -At 2pm
Register-ScheduledTask -Action $action -Trigger $trigger -TaskName “DailyScript” -Description “Run PowerShell script daily at 2 PM”
“`
In this example, the script creates a scheduled task to automate the execution of your desired script, allowing you to focus on other critical tasks.
5. Automating System Maintenance
Regularly monitoring and maintaining your system is crucial for optimal performance. With PowerShell, you can easily automate essential maintenance tasks to ensure that your system runs smoothly.
*Task:* Clear Windows event logs older than seven days.

4. Organize your script: Divide your script into sections for managing users and groups, such as creating users, updating users, deleting users, creating groups, adding users to groups, etc.
5. Create users: Use the `New-ADUser` cmdlet to create new users in the script:
“`
$FirstName = Read-Host “Enter the first name”
$LastName = Read-Host “Enter the last name”
$UserName = Read-Host “Enter the username”
$Password = Read-Host “Enter the password” -AsSecureString
$OUPath = Read-Host “Enter the OU path”
New-ADUser -Name “$FirstName $LastName” -GivenName $FirstName -Surname $LastName -SamAccountName $UserName -UserPrincipalName “[email protected]” -AccountPassword $Password -Enabled $true -Path $OUPath -ChangePasswordAtLogon $false
“`
6. Update users: Use the `Set-ADUser` cmdlet to update user information:
“`
$UserName = Read-Host “Enter the username to update”
$NewFirstName = Read-Host “Enter the new first name”
$NewLastName = Read-Host “Enter the new last name”
Set-ADUser -Identity $UserName -GivenName $NewFirstName -Surname $NewLastName
“`
7. Delete users: Use the `Remove-ADUser` cmdlet to delete users:
“`
$UserName = Read-Host “Enter the username to delete”
Remove-ADUser -Identity $UserName -Confirm:$true
“`
8. Create groups: Use the `New-ADGroup` cmdlet to create new groups:
“`
$GroupName = Read-Host “Enter the new group name”
$GroupScope = Read-Host “Enter the group scope (DomainLocal, Global, Universal)”
$OUPath = Read-Host “Enter the OU path”
New-ADGroup -Name $GroupName -GroupScope $GroupScope -Path $OUPath
“`
9. Add users to groups: Use the `Add-ADGroupMember` cmdlet to add users to groups:
“`
$GroupName = Read-Host “Enter the group name”
$UserName = Read-Host “Enter the username to add”
Add-ADGroupMember -Identity $GroupName -Members $UserName
“`
10. Save and run your script in PowerShell command-line as needed.
Remember to customize the script according to your organization’s requirements and use appropriate cmdlets for managing various aspects of AD users and groups.

}
“`
These are just a few examples of how you can leverage PowerShell command-line for automating server maintenance tasks in a Windows environment. The possibilities are nearly endless, making PowerShell an indispensable tool for IT professionals.
Can you provide real-world examples of automating file manipulation and data processing using PowerShell command-line?
Sure! Below are three real-world examples illustrating how to automate file manipulation and data processing tasks using the PowerShell command-line.
Example 1: Renaming multiple files
Suppose you want to rename all the text files in a directory from “.txt” to “.log”. You can accomplish this using the following PowerShell script:
“`powershell
Get-ChildItem -Path “C:ExampleDirectory*.txt” | ForEach-Object { Rename-Item $_.FullName -NewName ($_.Name -replace “.txt”,”.log”) }
“`
In this script, `Get-ChildItem` retrieves all the “.txt” files in the specified directory, while `ForEach-Object` iterates through the files and renames them using the `Rename-Item` command.
Example 2: Merging CSV files
If you have multiple CSV files containing data that you want to combine into a single CSV file, you can use this script:
“`powershell
$SourceFolder = “C:ExampleDirectoryCSVFiles”
$DestinationFile = “C:ExampleDirectoryMergedData.csv”
Get-ChildItem -Path $SourceFolder -Filter *.csv | ForEach-Object {
$CurrentFile = Import-Csv -Path $_.FullName
$CurrentFile | Export-Csv -Path $DestinationFile -Append -NoTypeInformation
}
“`
Here, `Get-ChildItem` locates all CSV files in the source folder, and `ForEach-Object` processes each file by importing its contents with `Import-Csv` and appending it to the destination file using `Export-Csv`.
Example 3: Processing log file data
Imagine you have a log file named “server.log” that contains various elements, including lines starting with the word “ERROR”. You could extract these error lines and save them in a separate file using the following script:
“`powershell
$LogFile = “C:ExampleDirectoryserver.log”
$ErrorFile = “C:ExampleDirectoryerror_lines.log”
Get-Content -Path $LogFile | Where-Object { $_ -match “^ERROR” } | Set-Content -Path $ErrorFile
“`
This script reads the log file’s content through `Get-Content`, filters the error lines with `Where-Object`, and saves them in a new error file using `Set-Content`.
