yeah — that took me a little while to figure out.
I still think I prefer ‘ls | wc -l’ to ‘(get-childitems .).count’. On the other hand, process stuff I like much better in powershell.

get-process | sort-object -property cpu -descending | select-object -first 20

makes a lot more sense than

ps -are -o “comm cpu” | head -20

The key to Powershell is remembering that every command returns an object. You then realize you can do stuff like this:

(Get-Process -name winamp*).Path
(Get-Process -name winamp*).VirtualMemorySize
(dir AUTOEXEC.BAT).CreationTime
(dir AUTOEXEC.BAT).CreationTime.Year

And then this

Get-Content c:\boot.ini | ForEach-Object { $_.Length }
