Consider this:

bash-2.03$ uname -s
SunOS
bash-2.03$ echo $SHELL
/usr/bin/bash
bash-2.03$ for i in ;
bash: syntax error near unexpected token `;'
bash-2.03$

[edk@sc-dev2 publish]$ uname -s
Linux
[edk@sc-dev2 publish]$ echo $SHELL
/bin/bash
[edk@sc-dev2 publish]$ for i in ;

This sounds good to me. It does mean avoiding a few short cuts which
bash provides, but nothing major (at least, nothing major which I've
seen so far). Still, until we've done that, it seems fair to specify
/bin/bash (IMO) ...
