Say you have a CSV file full of awesome, super great, amazing information. It’s perfect, except it’s missing a column. Luckily, you can use Select-Object along with the other CSV cmdlets to add a column.
In our example, let’s say that you have a CSV with two columns “ComputerName” and “IPAddress” and you want to add a column for “Port3389Open” to see if the port for RDP is open or not. It’s only a few lines of code from being done.
