How to get the line-count of all the files in a directory

Question

I'm asked to get the line count of all the files in some directory for which the path will be provided as a terminal argument.

My solution so far is:

wc -l "$1/"*

But doing this also gives me some unnecessary output like this:

wc: '/home/user/Desktop/Dir': Is a directory

So how can I print only the results for actual files not directories? And then how could I only display the ones that have been edited at most 10 minutes ago?

Answer 1

Thy this:

find ./pathToDirectory -type f -exec wc -l {} +
