如何在PowerShell属性vm中获取兆字节的Get-Process？

Question

I'm going to write command in PowerShell, which will output my process name and virtual memory. I need to change my value vm to megabytes.

Get-Process| Sort VM | Format-Table -p name,VM

And I have this

Name                                                                                    VM

Also I need to change color if process has > 100 Mb VM

Answer 1

The Format-Table cmdlet doesn't support coloring. What you can do is to change color for each row .

If you are willing to give up the nice table format, pass the results to pipeline and use Write-Host -ForegroundColor to specify colors on cell level. Like so,

gwmi win32_process | select name,processid,vm | % {
$params = @{ Object = $_ }
$mem = $params["Object"].VM/1MB
if([int]$mem -ge 100 ) {
    write-host -nonewline -foregroundcolor yellow $mem " "
} else {
    write-host -nonewline $mem " "
}
write-host $params["Object"].name " " $params["Object"].processid
}

Another an approach is based on saving the result on some temporary medium and add coloring later. This requires a bit more code. Petri has a nice example with more code than I'm willing to copypaste here.
