Another method to suppress output of return value.
# You can also rewrite "test | out-null" as "test > $null"

[^_^]PS[5]>function test { return $true }
[^_^]PS[6]>test > $null

Hi!

Why does Write-Output print an additional empty line when you use two consecutive "`n" in a string? And why doesn't Write-Host do that? See the examples below.

PS> Write-Output "abc`nABC`nabc"
abc
ABC
abc
PS> Write-Output "abc`nABC`n`nabc"
abc
ABC

abc
PS> Write-Host "abc`nABC`nabc"
abc
ABC
abc
PS> Write-Host "abc`nABC`n`nabc"
abc
ABC

abc
PS>

Great blog, by the way. Cheers!

Hi C-J,

This is a known issue.

Is it possible to suppress just the warning messages that pop on the screen during a command? For instance, if I do the following:

Get-mailpublicfolder -resultsize unlimited -erroraction silentlycontinue | ft Alias, PrimarySMTPAddress

I get several hundred warning mixed in with the output I am looking for. These warnings are from exchange 2003 objects that need some tidying up to be fully 2007 compliant (like leading spaces in alias names and such). I would like to be able to output just the filtered results to the screen and not display the warnings. Is this possible?
