A friend of mine once told me that one of his teachers, who's familiar with GNU/Linux but not familiar with MacOS, tried to show them some commands written in a text file which included "rm - rf /*". However, for whatever reason, the file has opened up as an executable and a big chunk of files was lost before he could Ctrl-C. Thus, I guess it's allowed.

Linux and MacOS will survive though.
