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!

PS C:\workspace> (gc “fileToParse.txt”) -notmatch "<criteria>" | out-file
"resultFile.txt"

Note: <Criteria>, for example, “not".

1. Open PowerShell

2. CD into directory to work on

3. Execute the following command:

get-childitem * -recurse | rename-item -newname { $_.name.ToLower() }
