Better option may be foreach ($item in Get-Process) { if ($Item.Responding) {write-host $Item.Name}} T Pops is right – changing True to False does nothing, because Responding is a boolean, and it seems “string” -eq boolean is always true.

Better option may be
foreach ($item in Get-Process) {
if ($Item.Responding) {write-host $Item.Name}}

Am I missing something or is a bad script or what? If you replace “True” with “False” in your example:

foreach ($item in Get-Process)
{if ($item.Responding -eq “True”){Write-Host $Item.Name}}

It produces the same result. Am I missing something or is a bad script or what?

How do I do this? I think I'd prefer an iterator for each class and just a for loop, iterating through each class until hasNext() is false. This is my java/c mind trying to figure out powershell though. Basically it all boils down to me wanting things out of two different Win32 classes both relating to harddisks and wanting their info to print together. for a temp fix, I'm just dumping stuff in an array in foreach loops, and then printing it in a for loop at the end. Seems like kind of a waste though... Thanks! foreach is great… unless you want to go through two objects simultaniously. How do I do this?

You’re not missing anything, there was a typo in the example:
Line: if ($val -eq 30)
Should be: if ($var -eq 30)

Then you would get “30 was found in array position 3″

I’ve made the correction in the tutorial.

You wrote it should be $i = 3. Now I won't say I'm not missing something...but what am I missing? Thanks.

The user is locked into a mode where the only valid input is "Y" whereupon the program terminates. The only choice the user has is to delay the inevitable. Asking "Are you sure you want to quit the application?" is kind of cheeky! Jerry Lee Ford’s example of getting user input is, perhaps deliberately, pointless.

Check "get-help sleep" for more info. { sleep 60 } cheers Eric,
