Depends on your shell, if you execute `which -a cd` it will show you /usr/bin/cd in addition to the built-in command. (zsh has which as a built in command, apparently bash doesn't, which causes the different output). It's unclear to me what /usr/bin/cd actually accomplishes though, even in bash. (final edit I hope, I found an explanation of sorts for /usr/bin/cd: https://unix.stackexchange.com/a/50060) |

Seems to be something they adopted from FreeBSD if the comment in the script is anything to go by ? (`/usr/bin/cd` is a shell script, you can cat it).
It seems something to do with it being a POSIX system if this SO answer[1] is anything to go by.
Beyond my paygrade though, and given Apple's shell appears to default to the built-in it seems I don't need to care either. :-)
