Find Any File can't seem to find what I'm looking for. Basically, I accidentally put in a plural in one of the defaults write commands:
defaults write com.apple.QuickTimePlayerX MGPlayMoviesOnOpen 1
And I want to get rid of it. I've verified its existence in Terminal with "defaults read | grep -i MGPlay," which gives me these two entries:
MGPlayMovieOnOpen = 1;
MGPlayMoviesOnOpen = 1;
Can deleting the second line be done through Terminal without knowing its exact location?
