等待工作不等待

Question

这里是代码

try{ 
    $SetupJob = invoke-command -ComputerName $j -Credential $credentials -ScriptBlock $sb -AsJob | Out-Null 

} 
catch [System.Exception]{ 
    continue 
} 

$SetupJob|Wait-Job 


$disable_command = "D:\PSTools\PsExec.exe $comp -u Administrator -p $str -accepteula powershell.exe c:\share\ps_disable.ps1" 
$CmdOutput = Invoke-Expression $disable_command 2>&1 



Remove-Item Z:\ps_*able.ps1 
Remove-Item Z:\setup.exe 

$SetupJob执行setup.exe上REMOTE_COMPUTER。执行后，它应该被删除。但是，我得到以下

Remove-Item : Cannot remove item \\remote_computer\share\setup.exe: The process cannot access the file '\\remote_computer\share\setup.exe' because it is being used by another process. 

如何解决？

Answer 1

请勿将Invoke-Command的输出传递给Out-Null。如果你这样做，那么$SetupJob将变为空，Wait-Job将立即返回。
