Question

I’m stuck on something that I know is really simple but for the life of me can’t figure out.

I’m trying to import a .txt file with a list of hostnames, which once retrived, the script returns the amount of totalphysicalmemory installed.

so far I have this:

function get
{
$boxes = Get-Content C:\Temp\hostnamesforRAM.txt
foreach($box in $boxes)
{
Get-WmiObject Win32_ComputerSystem | select TotalPhysicalMemory
}
}
get

however, it just simply returns this:

4151570432
4151570432
4151570432
4151570432
4151570432

Any ideas?

Thanks

You need to pass the current hostname ($box) to the computerName parameter, without it you’re getting the value from your own computer.

function get
{
$boxes = Get-Content C:\Temp\hostnamesforRAM.txt
foreach($box in $boxes)
{
Get-WmiObject Win32_ComputerSystem -ComputerName $box | select TotalPhysicalMemory
}
}

get

Another way, more shorter, would be to pass the content of the file to the ComputerName parameter. The ComputerName parameter accepts a collection of names:

Get-WmiObject Win32_ComputerSystem -ComputerName (Get-Content C:\Temp\hostnamesforRAM.txt) | 
Select-Object Name,TotalPhysicalMemory
