Starting with `emacs -q' I evaluate
(setq shell-file-name "bash -i")
in the *scratch* buffer and then do `M-x shell'. I get
apply: Searching for program: No such file or directory, bash -i
If I do
(setq shell-file-name "/bin/bash -i")
I get
emacs: /bin/bash -i: No such file or directory
Process shell exited abnormally with code 127
The trouble is that `shell-file-name' may be used much more widely than you expect.
