How to create a PowerShell script to check if txt files have more than 1 row of text?

Question

So I have alot of .txt files. I need for it to move txt files to a certain folder if they have more than 1 line. That is,

Text text text
Blah blah blah

But leave it alone if it's just

Text text text

Any suggestions on how to do this? This is on Windows XP if that helps. Thanks!

EDIT: Thanks John for your efforts. Figured out a way to do it in PowerShell

# Specify folder name that will contain the filtered .txt files
$goodFolder = "Filtered"

get-childitem *.txt | foreach ($_) {
$a = get-Content $_.fullname | Measure-Object

# If more than one line is found in text file, move it. Otherwise, leave it alone
If ($a.Count -gt 1) {   # If there is more than one line found in txt file
    Move-Item $_.fullname $goodFolder       # Then move it to a folder with text files with more than 1 line
}
}

Note: the original question was how do this in a .bat file.

This answer is a solution to the original question. It is not a powershell solution.

save this as clines.bat

@echo off
setlocal enabledelayedexpansion
set clines = 0
for /F %%J in (%1) do set /A clines = !clines! + 1
if %clines% LEQ 1 goto finis

rem @echo %1 has %clines% lines
move %1 %2

:finis
endlocal

and then call it in another batch file that iterates through the files

@echo off
for %%I in (*.txt) do call clines.bat %%I newfolder
