Sometimes it suits me…

if (!$displayOkStatus) {
    Write-Warning "Only connection errors will be displayed!"
}

while ($true) {
    try {
        $res = $ping.send($target)
        $status = $res.Status
        if ($status -ilike "Success") {

The script executes a commands stored in a variable (array). The output is conveniently collected and stored in a log file.

[string]$log = "c:\temp\log.txt"

[array]$commands = @(
    'if (!([System.Environment]::OSVersion.Version).Major -ge 6) {"win xp"} else {"win 7 or higher"}';
    'gps | select id,@{Name="WorkingSet(MB)";Expression={"{0:N1} M" -f($_.WorkingSet/1mb)}},name,company | sort name | ft';
    'netstat -noa -p TCP | findstr /i close'    
)
 
foreach ($command in $commands) {
    $command = [scriptblock]::Create($command)
    [array]$output = & $command
    $output | fl | Out-File -FilePath $log -Encoding UTF8 -Append 
}
