You can always avoid output, as far as I know. Anything output by a function is put onto the pipe. That's by design.
Give me a specific example where you think you can't avoid output? -----Original Message----- From: Joseph L.

Lol, Ok, an example (stupid, but an example)... Function Test_Time { $a = Get-Date If ($a.Minute -gt 30) { Return 1 } Else { Return 0 } } If (Test_Time) { Write-Host 'gt 30...' } Else { Write-Host 'lt 30...' } This works only by fluke as the only output is the return. What if the function necessarily generates loads of output? Function Test_Time { $a = Get-Date Get-Alias If ($a.Minute -gt 30) { Return 1 } Else { Return 0 } } If (Test_Time) { Write-Host 'gt 30...' } Else { Write-Host 'lt 30...' } This always evals to true as a result of the slew of output that gets written out. So how do you deal with this? I know I can hide the output of that Get-Alias, but what if you can't avoid some output?
