Would anyone who uses Bash regularly, both interactively and for scripting, really want to go back to using the V7 sh
for production work? I certainly would not.
A heretic!! Believers all know 'Bourne to Program, Type with Joy' and 'One true bracing style' are the two most important commandments of UNIX programmer!
Seriously, I still write my scripts as v7 and use (t)csh as my login shell on all my UNIX boxes ;-)
