Waiting for an process to quit in PowerShell

Is there a possibility to wait for an process to quit, without it needs to running? I know there is the keyword WaitForExit, but to use this the process needs to run.

My second question is, if there is a possibility to use an else-Statement in an while loop. Tried it already, but it always said that there isnt an function called else.

You can use wait-process cmdlet. Check link for details http://ss64.com/ps/wait-process.html

Example: wait-process -name notepad.exe

Do Until

Do {
    Sleep 5
} Until (Get-Process iexplore);

Will wait until iexplore is found

While

While (Get-Process iexplore) {
    Sleep 5
}

Will wait until iexplore is no longer running

Else after while

You cannot use an else statement after a while loop.

It needs to come after an if.

If you mean something like:

while (cond) {
} else {
}

?

Then NO. (how would the content of the else block be any different to code immediately following the while block?)

Is there a possibility to wait for an process to quit,

Yes. There are different ways of doing this, depending on the nature of the target process. Is it one created by the same script? Is the same session? A service? Or just an arbitrary process?
