Powershell psexec作业

Question

I tried this from another post at Stackoverflow:

$serverlist=$listbox1.SelectedItems

$jobs = foreach ($serverName in $serverlist) {
  Start-Job -Name "PingJob $serverName" -ArgumentList $serverName -ScriptBlock {
      param($serverName)
      if (Test-Connection -ComputerName $serverName -Count 1 -Quiet)
      {
        C:\Localbin\PsExec.exe -s \\$serverName ping cadc02 -n 30 > \\$serverName\pingresult\$serverName.txt
      }
   }
}

$jobs | Wait-Job 
$jobs | Receive-Job

It works and the output files are created, but the full data is missing. It just says

Pinging cadc02.xyz.net [192.168.100.2]

but the rest of the lines like

Reply from 192.168.200.3: bytes=32 time<1ms TTL=128
Ping statistics for 192.168.200.3:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

is missing.

How about this code:

$serverlist=$listbox1.SelectedItems

$jobs = foreach ($serverName in $serverlist) {
  Start-Job -Name "PingJob $serverName" -ArgumentList $serverName -ScriptBlock {
      param($serverName)
      if (Test-Connection -ComputerName $serverName -Count 1 -Quiet)
      {
        Invoke-Command -ComputerName $serverName -ScriptBlock { & ping cadc02 -n 30 } > "C:\temp\$serverName.txt"
      }
   }
}

$jobs | Wait-Job 
$jobs | Receive-Job

There is one big "if" with this code, and that is it uses Powershell remoting via the Invoke-Command instead of System Internals psexec.

If psexec is a requirement (you can't powershell-remote the computers for some reason) then this won't work for you.

Also: Change the "C:\\temp\\" in the code for a local folder that works for you.
