Program in rc shell[0]. It has a much superior syntax, and can manage piped commands. The use of the single quote to mean "really fucking quote", and $* working as every user would expect.. makes it a joy.

Secondly, I use rc in emacs shell-mode which poorly emulates a terminal, so advanced completion and all that other stuff I delegate to emacs. rc is just a programming language that supports shell commands extremely well.
