How to find the largest file in a directory and its subdirectories?

Question

We're just starting a UNIX class and are learning a variety of Bash commands. Our assignment involves performing various commands on a directory that has a number of folders under it as well.

I know how to list and count all the regular files from the root folder using:

find . -type l | wc -l 

But I'd like to know where to go from there in order to find the largest file in the whole directory. I've seen somethings regarding a du command, but we haven't learned that, so in the repertoire of things we've learned I assume we need to somehow connect it to the ls -t command.

And pardon me if my 'lingo' isn't correct, I'm still getting used to it!

Quote from this link-

If you want to find and print the top 10 largest files names (not directories) in a particular directory and its sub directories

$ find . -type f -printf '%s %p\n'|sort -nr|head

To restrict the search to the present directory use "-maxdepth 1" with find.

$ find . -maxdepth 1 -printf '%s %p\n'|sort -nr|head

And to print the top 10 largest "files and directories":

$ du -a . | sort -nr | head

** Use "head -n X" instead of the only "head" above to print the top X largest files (in all the above examples)
