Vista - Find a string within a variable string

I'm still learning PowerShell, and here's what I'm trying to
accomplish.

Find out what service pack version my machines are running and then
save this information to a file.

The way I'm going about this task is:
1. I'm going to feed the computer netbios name to the ps script.
2. The ps script will find this information and match the netbios name
to the service pack version
3. Write this information to a file and append to it until it's done.

So far, I'm able to pass a parameter to the script and get the service
pack version; however, I can't figure out how to find a string within
the variable string that holds the results.

Here's what I have so far:
# Handle parameter received from users
param( [string] $ComputerName )


$SpFound = Get-WMIObject Win32_OperatingSystem –Property
ServicePackMajorVersion –Computer $ComputerName


Any suggestions will be greatly appreciated.

Hi Edward,

I have to admit I don't completely understand what you mean, but how
about this:-

function process-servicepack ($Hostname) {
$a = gwmi win32_operatingsystem | Select-Object
"ServicePackMajorVersion"
$a -match "\d" | Out-Null ; $v = $matches[0]
Add-content -path "C:\servicepacks.txt" -Value "Netbios Name :
$hostname`tServicepack : $v"
}

Get-Content "C:\computers.txt" | % {process-servicepack $_ }

Where "C:\computers.txt" is your list of Netbios names. One on each
line.
Where "C:\servicepacks.txt" is your output file containing the result
( I think ) you want.

Hope it helps,

Stuart

Whoops, in my mad rush to post I made a little mistake; I forgot to
put the -computername parameter and value in the gwmi line.
This is the correct code:-

--------------
function process-servicepack ($Hostname) {
$a = gwmi win32_operatingsystem -ComputerName $Hostname | Select-
Object "ServicePackMajorVersion"
$a -match "\d" | Out-Null ; $v = $matches[0]
Add-content -path "C:\servicepacks.txt" -Value "Netbios Name :
$hostname`tServicepack : $v"
}

Get-Content "C:\computers.txt" | % {process-servicepack $_ }
---------------

Sorry about that. The above ought to do what you need...if I
understood properly(!)

Regards,
Stuart

I suggest using Quest software which is a free download, it can search for
computer services packs, etc in a liner.

Yes, it was exactly what I needed. I'm just going to go over the code,
that way I can understand how you accomplished the task.

Thanks again.
