Re: Should this be this way?

[Greg Wooledge]

POSIX specifies the behavior of a shell.  This tells Chet how he has to
make Bash behave (with some leeway).  There are all kinds of silly little
details and ambiguities that Chet has to worry about.

However, YOU as a shell script writer do not have to worry about all
that crap.  All you have to do is put the proper shebang line in your
script, and then -- like magic! -- your script will be executed using
the interpreter you specified.

End of problem.
