Write-Host question

Below is my test.ps1 script
When I run it, PowerShell nicely 'groups' the results without repeating the
headers.


Name Condition
---- ---------
name1 True
name2 False
name3 True


What I'd like to do is when the 'Conditon -eq False' turn that line red.

Do I need to build up the results in an array, print out the headings, loop
through it and do a
'write-host -f red' ?

Or is there a PowerShell shortcut that I can ?


<script>
function New-Item
{
"" | Select Name, Condition
}

function New-Result ($name, $condition)
{
$obj = New-Item
$obj.Name = $name
$obj.Condition = $condition

$obj
}

New-Result "name1" $true
New-Result "name2" $false
New-Result "name3" $true
</script>

Well, this might do something like what you want:

$results = (New-Result name1 $true), (New-Result name2 $false),
(New-Result name3 $true)

$oldColor = $host.ui.rawui.foregroundColor
$results | ? { $_.Condition }
$host.ui.rawui.foregroundColor = 'red'
$results | ? { !$_.Condition }
$host.ui.rawui.foregroundColor = $oldColor

Although it may print two tables. If you want it to print only one
table, you can try editing the PowerShell formatting file (or creating a
new one and importing it with Update-FormatData).

Hi,

You might want to try adapting this code:

$a = 1, 2, 3, 4, 5
foreach ($element in $a){
if ($element % 2){write-host $element}
else
{write-host $element -foregroundcolor red}
}

I'm not aware of a simple way to do it using format-table.
