How to find the lowest numbered computer on a network - powershell

Question

I am attempting to write a script to copy some information from one computer to another. The first computer has a name similar to "SERVERxx" where xx is the site number. There are multiple computers on the network with names similar to "TERMINALxx_yy", where xx is the site number and yy is the number of the TERMINALS. What I would like to do is find the lowest numbered of the "TERMINALS" (as 1 may not always be the lowest). There is an environment variable on the SERVER named TERMSTR that is equal to "TERMINALxx_", as well as an environment variable named NUMTERMS that is the number of TERMINALS at the site.
The most I've been able to figure out is:
net view | Select-string $termstr
But that just gives the table output.
I'm figuring I need to first have NET VIEW give just the computer names, then sort in descending order and select the first one.
Thanks

Answer 1

if you absolutely MUST use net view, then this will give you the highest lowest system number with the header, footer, line padding, and non-digits removed. it does not add any leading zeros to the resulting number, tho. [grin]
net view |
# skip the 3 header lines
Select-Object -Skip 3 |
# skip the footer lines
Select-Object -SkipLast 2 |
# trim away the "net view" line padding
# remove the non-digits
ForEach-Object {
[int]($_.Trim() -replace '[^0-9]')
} |
Sort-Object |
Select-Object -First 1

Here is a starting point of code you can use.
$Servers = Get-ADComputer -Filter 'Name -like "SERVER*"'
foreach($Server in $Servers | Sort-Object){
$N = $Server.name.substring(($Server.name.length)-2)
$Terminals = Get-ADComputer -Filter 'Name -like "TERMINAL$($N)*"'
$count = $Terminals.Count
$Terminal = $Terminals | Sort-Object
$TerminalZero = $Terminal[0].Name
Write-Host "Terminal Name: $TerminalZero"
$COMMAND = {
Write-Host [System.Environment]::GetEnvironmentVariable("termstr","Machine")
[System.Environment]::SetEnvironmentVariable("TERMSTR", $TerminalZero, "Machine")
[System.Environment]::SetEnvironmentVariable("NUMTERMS", $Count, "Machine")
}
Invoke-Command -ComputerName $Server -ScriptBlock { $COMMAND }
}
}
