[No easy way to do that]


Yes! I was asking about this in gnu.emacs.help not so long ago
(address@hidden thread). Kevin Rodgers pointed out to me that
one could set the variable `sh-shell' as a file local variable to have a
given script recognized as a given shell type. This works (mostly), but
still leaves the mode-line saying "[bash]" in all cases. That can be fixed
with mode-line-process: "[tcsh]" (or whatever).

I agree it would be nice if there was some easy way to switch sh-mode
between the various different shell flavours with no side effects.
