Question

hey im trying to build a powershell script that will pull a serial number from a remote pc and then match that against an xlsx file which would then match a column against another xlsx file i have gotten to the point where i can pull the remote sn and have everything put in to a csv output but i am having issues matching the data then filtering based on the match and then outputting only what i need im new to scripting so im pretty sure its more my lack of experiance than anything else this is my code so far
$computers = Get-Content c:\script\computerlist.txt
Get-wmiobject Win32_Bios -ComputerName $computers | Select-Object __SERVER, SerialNumber| Format-Table |out-file C:\script\computerinfo.txt
$computerinfo = Import-Excel C:\script\compDB.xlsx
$userinfo = Import-Excel C:\script\userDB.xlsx
$Computerinfo[2].SERIAL -eq
$Computerinfo[2].DATE_ADDED
$Computerinfo[2].OS
$Computerinfo[2].MODEL
$Computerinfo[2].USER
$userinfo[2].NAME_FIRST
$userinfo[2].NAME_LAST
$userinfo[2].NT_USERID
''
'Computer Info'
'----------'
$computerinfo ,$userinfo | Format-Table - | Out-File c:\script\computerinfo.csv

Answer 1

First you need to save the wmi information to a variable:
$WMIinfo = Get-wmiobject Win32_Bios -ComputerName $computers | Select-Object __SERVER, SerialNumber
Then you would need to loop through the spreadsheet and compare to data in Computer spreadsheet. If it matches loop through user spreadsheet for match:
foreach ($CompEntry in $Computerinfo) {
if ($WMIinfo.serial -eq $CompEntry.serial) {
foreach ($UserEntry in $userinfo) {
if ($UserEntry.NT_USERID -eq $CompEntry.USER) {
#output information you want here
}
}
}

I'll try to help you get there.
I created an Excel file called Serial.xslx. Here's what it looks like
SerialNumber DeployedTo
212 Ham
4M24N32 Stephen
I then import this as $list.
$list = import-excel C:\temp\serial.xlsx
Next,to get the Win32_Bios info, so I can grab the SerialNumber property.
$bios = get-WmiObject Win32_Bios
Finally, I'll filter through the $list (which contains the Excel file), and find a row which has a SerialNumber that matches this computers serial number. If I find a matching one, then I grab the .DeployedTo value for that record.
$user = $list | Where SerialNumber -eq $bios.SerialNumber | Select -ExpandProperty DeployedTo
All that remains is to demonstrate that it works.
"the computer with serial $($bios.SerialNumber) is deployed to $user"
>the computer with serial 4M24N32 is deployed to Stephen
Now, you've got two separate excel files, so I would either manually join them into one, or repeat this same basic approach.
