Having trouble finding a word in multiple files

[Pat Brown]

I've tried a variety of grep commands but I can't find the specific
word I'm searching for that is in a file or files somewhere in my
Dropbox folder. The word I'm trying to find is Blowback. Can someone
please help me with the correct command?
