To give an example ...

rudi@tenfore:~> bash -c ". .bashrc"
rudi@tenfore:~> sh -c ". .bashrc"
sh: line 0: .: .bashrc: file not found

Yep! But the most perfide thing is: some of the bashisms still work.

If a script still works with "/bin/sh -> bash", do the test again,
with "/bin/sh -> ash", as not even zsh, nor (t)csh are disabling all
the "extras" when called as /bin/sh .

Happy debugging! (I've killed more than 2500 hours on such sh.t)
