Just wondering what the recommendations were for online places to learn powershell? I have a specific task I'm trying to achieve around iterating through all subfolders (only one level), renaming each file with a certain extension to its current name plus subfolder name, then moving the resultant file into the root directory. Up for teaching myself but there seems to be a lot of crap online so was wondering if there were any known good places to learn.
Cheers.
