[英]Getting error output from a powershell 2.0 script running as a task
[英]Powershell 2.0: Getting different results when running a remote session from a script vs typing it in manually. What's the difference?
從腳本運行遠程會話與手動輸入確切的命令序列時,我得到了不同的結果。 這發生在我正在處理的相當復雜的腳本中,但我創建了一個很小的腳本來演示這個問題。 返回的數字不應該是 7-5-7,而不是 7-5-5?
有問題的腳本
$oldMachineName = "ppal12084229"
$remoteSession = New-PSSession $oldMachineName
$xyz =7
"outside remote session"
$xyz
""
enter-PSSession $remoteSession
$xyz = 5
"inside remote session"
$xyz
""
exit-pssession
"outside remote session"
$xyz
""
remove-pssession $remoteSession
當我運行腳本時,我得到以下輸出:
outside remote session
7
inside remote session
5
outside remote session
5
但是,當我手動輸入命令時,我得到以下信息:
PS H:\> $oldMachineName = "ppal12084229"
PS H:\> $remoteSession = New-PSSession $oldMachineName
PS H:\> $xyz =7
PS H:\> $xyz
7
PS H:\> enter-PSSession $remoteSession
[ppal12084229]: PS C:\WINDOWS\system32> $xyz = 5
[ppal12084229]: PS C:\WINDOWS\system32> $xyz
5
[ppal12084229]: PS C:\WINDOWS\system32> exit-pssession
PS H:\> $xyz
7
PS H:\> remove-pssession $remoteSession
為什么我得到不同的結果?
Enter-PSSession
和Exit-PSSession
用於交互式使用。 在你的腳本中試試這個,看看你得到了什么:
$oldMachineName = "ppal12084229"
$remoteSession = New-PSSession $oldMachineName
$xyz =7
"outside remote session"
$xyz
""
invoke-command -Session $remoteSession -ScriptBlock {
$xyz = 5
"inside remote session"
$xyz
""
}
"outside remote session"
$xyz
""
remove-pssession $remoteSession
