替代追加出口CSV PowerShell的

Question

我添加用戶登錄和註銷跟蹤腳本

我發現，一些計算機不導出CSV，因爲他們的PowerShell 2.0，因爲不支持附加有什麼選擇？

$ErrorActionPreference = 'Continue' 
####**** Tracking user logon *****##### 

$username = $env:USERNAME 
$computername = $env:COMPUTERNAME 
$ipv4 = Test-Connection -ComputerName (hostname) -Count 1 | foreach { $_.ipv4address } 
$ipv6 = Test-Connection -ComputerName (hostname) -Count 1 | foreach { $_.ipv6address } 
$timeformat='MM-dd-yyyy hh:mm:ss tt' 
$time = (Get-Date).ToString($timeformat) 
$action = 'Logon' 
$filedate = 'MM-dd-yyyy' 
$filename = 'CompInfo' + ' ' + $(Get-Date).ToString($filedate) 

#Creates custom table and sorts the information 
$table= New-Object –TypeName PSObject -Property @{ 
      'Date/Time' = $time 
      'Username' = $username 
      'ComputerName'= $computername 
      'IPv4 Address' = $ipv4 
      'IPv6 Address' = $ipv6 
     'Notes/Action' = $action 
} | Select date/time, username, computername, 'IPv4 Address', 'IPv6 Address', notes/action 
$table | Export-Csv "d:\$env:username.csv" -NoClobber -append -NoTypeInformation
