Test whether a variable has anything in it so a script can continue - if($var1 -gt 0)

[a2alpha]

Hi,

I was wondering how you perform a test to see if a variable created from a previous command has got anything in it. My script keeps failing because it is comparing it to 0 with a if greater than.

For example I have:

$var = get-vm

if i want to test whether there is anything in it how do I make the following test:

If($var -gt 0)

{

$var

}

else

{

"nothing in variable"

}

It seems sometimes it works others it throws one of those red errors.

Thanks in advance for any help,

Dan

I normaly use:

If ($var) {
	$var
} else {
	"nothing in variable"
}

If you want to do the oposite it would be:

If (-not $var) {
	$var
} else {
	"nothing in variable"
}
