In PowerShell, how to combine the results of two commands that have a 1-to-1 relashionship?

In PowerShell, you can combine the results of two commands that have a 1-to-1 relationship using the foreach loop to iterate over one of the collections and then access corresponding elements from the other collection. Here's a general example:

# Execute your first command and store the result in a variable
$command1Result = <Command1>

# Execute your second command and store the result in another variable
$command2Result = <Command2>

# Check if the lengths of both results are equal (indicating a 1-to-1 relationship)
if ($command1Result.Count -eq $command2Result.Count) {
    # Loop through one of the collections (assuming both collections have the same length)
    for ($i = 0; $i -lt $command1Result.Count; $i++) {
        # Access corresponding elements from both collections using the loop index
        $item1 = $command1Result[$i]
        $item2 = $command2Result[$i]

        # Now you can perform operations using $item1 and $item2, which represent corresponding elements from both collections
        Write-Output "Item from Command1: $item1, Item from Command2: $item2"
    }
} else {
    Write-Output "The number of items in the results of both commands does not match."
}

Replace <Command1> and <Command2> with your actual commands. This script will execute both commands, store their results in variables, and then iterate over one of the collections (assuming both have the same length). It accesses corresponding elements from both collections using the loop index and allows you to perform operations using those elements.
