Editing Scripting Basics (section)

==== PowerShell ====

This script queries all computer objects in Active Directory and checks which ones respond to ping.

<syntaxhighlight lang="powershell">
# Get all Active Directory computer names and test if they are reachable

# Query all computer objects in Active Directory
Get-ADComputer -Filter * |

    # Extract only the 'Name' field (hostnames)
    Select-Object -Expand Name |

    # For each hostname, test network connectivity
    ForEach-Object {
        if (Test-Connection -Quiet $_) {
            # If reachable, print confirmation message
            "$_ reachable"
        }
    }

# Notes:
# Test-Connection is equivalent to 'ping'
# -Quiet returns only $true or $false (no output text)
