shells (was Re: UNIX V7)

Back when I was using BSD on VAXen from 1983-1986 or so, everyone around me thought csh was the greatest thing since sliced bread (though I don't personally think that sliced bread is such a great invention). Every time they had to edit a shell script they had trouble because they had wired their brains for csh. I didn't want to learn two incompatible shell syntaxes, especially since at that time csh didn't support some of the sh features I tended to use a lot, such as some of the less common I/O redirections. (I assume that csh has gained support for those since then.) I used ksh starting around 1987. Sometime around 1989 or 1990 I switched to bash. People have tried to convince me that I'd be happier with zsh, and I'll admit that it has some cool features, but nothing sufficient to lure me away from bash. I've used csh enough that I can live with it if I'm forced to do so. Several companies I've worked for have set csh as the default shell and made it difficult to change, apparently thinking that this will somehow reduce the workload of their IT support staff. Eric
