Call a command line command and process the output

Powershell scripts can call standard command line commands and then process the output.

$FSUoutput = fsutil.exe 8dot3name query c:
$DIRXoutput = cmd.exe /c dir C:\ /x

foreach ($line in $DIRXoutput)
    {
        if ($line -like "*progra~1*") {$8DOT3NamesExist=1}
    }

if ($8DOT3NamesExist -ne 1) {$ERRORCODE+=1}


foreach ($line in $FSUoutput)
    {
        #Checks FSUtil output reports C: is 8dot3 enabled
        if ($line.StartsWith("The volume state is"))
            {
            #Checking for 0
            $line=$line.Remove(22)
            $line=$line.TrimStart("The volume state is: ")
        
            $line = $line/1
            
            $CVSTATE = $line
