It could be Ed, I remember the documentation differently, so I could be
not remembering it correctly, so I'll keep quiet now.
The original version of 'cp' (by which I mean the version going back to

file contents to a different file. There was no question of using
links, hard or soft (in fact symbolic links hadn't been invented).
