如何在PowerShell中抑制Start-Job命令的作业对象信息显示？

Sure thing! There are a couple of easy ways to prevent that job object table from appearing when you run Start-Job in PowerShell. Here are the most reliable methods:

• Capture the job in a variable: This stores the job object for later use (like checking its state or retrieving results) while keeping the console clean. Example:

  $bandwidthJob = Start-Job -ScriptBlock { param($piCurrentBandw) ... } -ArgumentList $yourValue
  

  No output will be printed, and you can still reference $bandwidthJob if needed.

• Redirect output to $null: If you don't need to keep track of the job at all, send the output to the null device:

  Start-Job -ScriptBlock { param($piByteTotalsec) ... } > $null
  

  For a more PowerShell-native approach, use Out-Null which handles all output streams:

  Start-Job -ScriptBlock { ... } | Out-Null
  

• Use a throwaway variable with -OutVariable: The -OutVariable parameter lets you capture the job object in a variable you don't intend to use. A common convention is to use an underscore for this:

  Start-Job -ScriptBlock { param($piPacketssec) ... } -OutVariable _
  

  This captures the job in $_ (which is overwritten quickly in most contexts) and stops the table from showing up.

All these methods work because Start-Job emits the job object as output by default. By capturing or redirecting that output, you prevent it from being displayed in your console.
