Okay, this probably sounds dumb for anyone who knows the answer, but I'm completely lost. I have to use the head command to search a directory AND all of its subdirectories to display the first line of all .txt files. I know how to do this: head -1 ~/UnixCourse/*.txt, but that does not search the subdirectories. I've tried to figure it out on my own and use help resources, but had no luck. I would really appreciate if someone could save me a little time and effort by helping me out here.

look into 'man find'

I've looked into find and understand how to make that work with subdirectories, but I have not seen any way to use it with the "head" command. Am I missing something or was I just not clear that I need to use the head command to get the first lines of each file?

Look at the -exec part of the man page....

Cheers

Ahh got it now, thanks I had tried it once before but did not use the {}'s correctly so could not figure it out. Thanks again for the help!
