Powershell，我输入一个列表收集数据和 output 整个列表到一个 CSV

Question

I am creating a script that reads a list of computer names and collects data from security event logs about who is on the computer, how long they have been on for, and how long it has been since the computer has restarted. I have it working except that it does not output all the data into one CSV. I just receive one CSV file with one computer name.

function Get-KioskInfo {

    param (

        [parameter(ValueFromPipeline=$True,ValueFromPipelineByPropertyName=$True,Position=0)]
        [Alias('PSComputerName','DNSHostName','CN','Hostname')]

        [string]
        $ComputerName = $env:COMPUTERNAME
        )
        #PARAM
        $User = try {(Get-WmiObject -ComputerName $ComputerName Win32_ComputerSystem | Select-Object -ExpandProperty username).trimstart("NG\")} catch {Write-Output "User not detected";break}
        $BootStart = ((get-date) - (Get-CimInstance win32_operatingsystem -ComputerName $ComputerName).LastBootUpTime).Days
        
        #These variables are for the DATE & Time calculation
        If ($user -NE $null) 
            { Write-Verbose 1
            # Do something
            $Date1 = Get-date
            Write-Verbose 2
            $SP = Get-WinEvent -ComputerName $ComputerName -FilterHashTable @{LogName = "Security";ID="5379";Data=$User; StartTime=((Get-Date).AddDays(-1))}
            Write-Verbose 3
            $Date2 =($SP | select -first 1).timecreated
            Write-Verbose 4
            $USERLOGTIME = ($Date1-$Date2).hours.tostring("N2")
            Write-Verbose 5
            }
        else{Write-Output "No user";break}
        Write-Verbose 6

Continuing from my comment. I too wonder why the use of jobs for this use case. Unless you are doing this on hundreds of computers, thus needing parallel processing.

This refactor/formatting is just my way of making sense of what you posted. I'm old, and crowded code just really hurts my eyes. ;-} Yet, code the way you like of course. ;-}

I do not have an environment to test this, but give it a shot.

function Get-KioskInfo 
{
    param 
    (
        [parameter(ValueFromPipeline = $True,ValueFromPipelineByPropertyName = $True,Position = 0)]

        [Alias(
            'PSComputerName',
            'DNSHostName',
            'CN',
            'Hostname'
        )]
    
        [string]
        $ComputerName = $env:COMPUTERNAME
    )

    ($User = try 
             {
                (Get-WmiObject -ComputerName $ComputerName Win32_ComputerSystem | 
                Select-Object -ExpandProperty username).trimstart("NG\")
             } 
             catch 
             {
                 'User not detected'
                 break
             }
    )

    ($BootStart = ((get-date) - (Get-CimInstance win32_operatingsystem -ComputerName $ComputerName).LastBootUpTime).Days)

These didn't help me with my solution, but you were right about the start-jobs. I have to rework the entire script in order to get the correct info.
