That used to be the case, but these days 'sh' is as often an alias to
a lighter shell program, a free reimplementation of sh that includes a
much smaller superset of the original sh functionality than that of
bash.  For example, on default Ubuntu installations, sh is a symlink
to dash, "a lightweight POSIX-compliant shell derived from ash."
