PowerShell: Extracting certain lines in any file

I had quite a large file that I needed to parse, and the challenge was to extract certain lines that didn’t match a certain condition. The solution . . . PowerShell, like so:

select-string -path filename -notmatch "criteria" | foreach {$_.line} | out-file -filepath filename -encoding ascii

That’s it!

Cut-and-paste not working via RDP

Cut-and-paste wasn’t working from me between my RDP session to an XP box from my Windows 7 box. Apparently, the problem was rdpclip.exe wasn’t running. So, if you come across the same issue, check for that process and turn it on if necessary via Run > type rdpclip.
