Powershell Parsing

In PowerShell, Get-WMIObject is a terrific cmdlet for remotely managing systems. If you have a text list of server or computer names, here's a quick method you could enumerate that list and do something to each server.

foreach ($server in (Get-Content s:\servers.txt)) {
#skip blank lines
if (($server).length -gt 0)
{ $server
Get-WmiObject win32_operatingsystem -computer $server.Trim()}
}

S:\Servers.text is just a text file like this:

Server1
Server2
DC1
Server3

The ForEach loop reads the contents of the file, assigning the name to $server. I've added some code to catch blank lines that sometimes end up at the end of files like this. If the length of $server is greater than 0 than process the server. The code sample will echo the name to the console and then run the Get-WMIObject cmdlet passing $server as the computername. I found it helpful to call the Trim method as an extra space can confuse PowerShell.
