sh is just the system shell. On some platforms it is
a binary, sometimes a symlink. Invoking sh gets you
bash sometimes, on some platforms. On some
platforms it is dash. Others ash. There is not *one*
answer to the question in the general case. However,
it is not even always relevant as to what /bin/sh
is. Any script might have a #!/bin/bash at the top
to force use of bash.
