sh shell

Hi!

I have FreeBSD 14.0-RELEASE-p2. Root shell is sh and user ksh.
In the root directory is .shrc and .sh_history which settings using if I
log as root or su -. But if I use just su if as I read should use also
root settings but it doesn't. It use .cshrc. Is it correct or I have
somewhere wrong setting, please?

env
