It seems to me that it is a little late in the day to be changing
to bash. Some well known Linux distributions are beginning to see
that some non-posix features of bash can create difficulties. I
believe recent releases of Ubuntu use dash as the prefered
shell, and it looks as though Debian will be going the same way.
Dash is supposed to be a modern, faster and cleaner
implementation of sh -- if installed through FBSD ports it has
the same man page as sh.

I'm also a long time csh/tcsh user (somewhat more than 20 years)
and freely admit that redirection at the command line can
occassionally be a problem. I've always used sh for any serious
scripting.
Unless you wish to play with one or other fairly common but
lesser known shells such as zsh or ksh then I would suggest that
sh or dash (perhaps with a -E or -V option for interactive use)
would be more appropriate than bash in a modern OS.
But ultimately each to his own.
Good luck,
Malcolm
