Re: Need a new book
Umm.
Sort of.
It's more often used in something like this
get-disk | where-object {$_.PartitionStyle -eq "MBR" | ft number, friendlyname
So you are getting details of all your disks as objects, looking within each object for the PartitionStyle equaling MBR and displaying some other info about the disk
For disk you could also do $_.Model, $_.NumberOfPartitions, $_.Size and so on
I've read a few articles that describe $_ as the variable of the pipeline if that makes more sense.
i.e. get-disk puts the disk objects into the pipeline and you can then look up their values using $_
