Check text file for text and move depending on if that text is fou

I'm a newbie when it comes to PowerShell but I think it will do what I want
it to do. I just need some help getting started. I would like to look at
the files in a directory l:\mdr2000 and if they are of a certain type with an
extension .000, examine the contents of those files for the text 'M-460-2'.
The files with the .000 extension are text files. If they contain the text
'M-460-2', I'd like to move the file to a directory v:\cas\a2000. If the
text is not present, I'd like to move the file to another directory
l:\mdr2000\tested. Could someone help me with some code to do this? Thanks
in advance for the help.

 

I don't know how to do it with PowerShell but here is a batch file
solution:
@echo off
setlocal enabledelayedexpansion
set string=M-460-2
set source=l:\mdr2000
set target1=v:\cas\a2000
set target2=l:\mdr2000\tested
if not exist "%target1%" md "%target1%"
if not exist "%target2%" md "%target2%"
for %%a in ("%source%\*.000") do (
set target=%target2%
find /i "%string%" "%%a" > nul && set target=%target1%
echo move "%%a" "!target!"
)

Remove the word "echo" in the line with the "move" command
to activate the batch file.
