Hello, Every year, my students are completely taken aback when trying to copy a directory:
$ cp /foo/bar . omitting directory /foo/bar The problem is that the error message is not explicit at all about what issue cp actually encountered: "yes it is a directory, so what?!" Could this be changed into for instance: $ cp /foo/bar . not recursing into directory /foo/bar by default which will help them figure out they just need to use -r. Samuel
