I'm going on some old memories here, so I cannot provide a very
detailed explanation, but the reason /usr/bin/cd exists is due
to a POSIX requirement that relates to aliases and being able to
not use an alias via escaping. But /usr/bin/cd is a useless
script since if you run cd within a shell script the directory
change only applies to the subshell under which the script runs.
cd cannot be a shell script.
Also, the script is a generic script in that it is used for a
number of commands and not just cd.
I noticed that /usr/bin/cd has a hard link count of 15 on my
10.4 system. So I looked at the inode number for /usr/bin/cd
(run 'ls -i /usr/bin/cd') and then ran
find /usr/bin -inum number_from_ls -print
All of these are the same script
$ find /usr/bin -inum 51616 -print
