How do I find a .txt file that is in Documents by using the terminal?

If you know exact name:
$find / -name "hello.txt"

If you are not confident about case:
$find / -iname "hello.txt"

Avoid searching in "/" as it'll search whole file system. Search "/home/" instead.

Thanks, but I keep getting permission denied over and over on this search plus with my lab assignment with typing in the correct path to the file I also get the same thing "permission denied". Please help.

Use

fine ~/ -iname "hello.txt"

Which will stay within your home folder where you should have no problems with permissions.

What is the path to file where you are having permissions problems?

type

ls -l fullpathtothefile

and show us command and the output sent to the screen.
