Hi Raúl you don't specify in your report which directory where you run the command $ quickly create ubuntu-cli example
It may be a permission problem in the directory. You could try these commands to verify.
$ mkdir example $ mkdir example/bin $ echo gedit > example/bin/example $ chmod u+x example/bin/example $ ./example/bin/example
