貌似 Mac OS X 下 sudo su root 的时候不会执行 /etc/bashrc，原因是什么呢？

The main difference is that /etc/bashrc is not automatically read under any circumstance. The only way it gets included (say in ~/.bashrc), is if it's referenced in your ~/.bashrc file with something like:

if [ -f /etc/bashrc ] ; then
. /etc/bashrc
fi

/etc/profile is read automatically only if you are loginning in.
