what's the local profile for /bin/sh
 

just as .bashrc to /bin/bash?

In Fedora there is sh just the symbolic link to bash. So .bashrc and .bash_profile are used.

thanks,
but what's the profile for the 'real' sh?

On most systems, sh is just a symbolic link to bash. Therefore, you dont't actually have sh.

Presumably, if you did, it would use ~/.profile, like bash.
