[PowerShell每日技巧]保留指向进程的句柄(20140221)

DAIC

When you launch an EXE file, PowerShell will happily start it, then continue and not care about it anymore:

PS C:\> notepad PS C:\>

If you'd like to keep a handle to the process, for example to find out its process ID, or to be able to check back later how the process performs, or to kill it, use Start-Process and the –PassThru parameter. This returns a process object:

PS C:\> $process = Start-Process -FilePath notepad -PassThru PS C:\> $process.Id 5936 PS C:\> 'You just launched process {0}.' -f $process.Id You just launched process 5936. PS C:\> 'CPU consumption in seconds so far: {0}.' -f $process.CPU CPU consumption in seconds so far: 0.1092007. PS C:\> $process.CloseMainWindow() True PS C:\>
