Thanks for the nice repo with the commentaries! Here is the code for cp: https://svnweb.freebsd.org/csrg/bin/cp/cp.c?revision=69112&view=markup https://svnweb.freebsd.org/csrg/bin/cp/utils.c?revision=66606&view=markup A challenge: where does the code distinguish src from src/ ? Indeed it behaves like rsync, but we read in the source something that seems to contradict it: /* * Cp has two distinct cases: * * cp [-R] source target * cp [-R] source1 ... sourceN directory * * In both cases, source can be either a file or a directory. * * In (1), the target becomes a copy of the source. That is, if the * source is a file, the target will be a file, and likewise for * directories. * * In (2), the real target is not directory, but "directory/source". */ Was it a bug? BTW, I do not remember this behaviour in SunOS, but also not in FreeBSD when I used it many years ago, although it was there. Rodrigo
