Yes, but when bash is invoked as sh it changes its behavior to mimic the
historic sh.

So while everyone uses a symlink from sh to bash, that "sh" command behaves very
differently than calling bash.

See
http://www.faqs.org/docs/bashman/bashref_63.html

"If Bash is invoked with the name sh, it tries to mimic the startup behavior of
historical versions of sh as closely as possible, while conforming to the POSIX
standard as well."
