How can i verify if a process is already running on powershell?

问题

i have the following code

Start-Process -windowstyle minimized "C:/xampp/xampp-control.exe"

There is a way to know if process is already running?

回答1:

One way to do this is to get the process ID of the process (use the -PassThru parameter of Start-Process) and then you can see if the process exists by ID. Example:

$processId = (Start-Process notepad -PassThru).Id
if ( Get-Process -Id $processId -ErrorAction SilentlyContinue ) {
   "Process is running"
}
