I am sure this has been discussed here before (search the list
archives), although I can't find it in the FAQ.

Your output suggests that when Emacs sends a command to bash, the
command is terminated with a DOS-style <CR><NL> combination, while the
shell only expects <NL>.  (When bash sees command "ls\r" it naturally
can't find that, and when Emacs gets the response output "ls\r:
command not found" that looks like what you show above.)

This may also depend on your Cygwin configuration, like when you have
something about "binmode" in your CYGWIN environment variable (which
is of course expected to create problems with non-Cygwin tools).  I
haven't tested this, though.

process-coding-system-alist to tell Emacs to use Unix-style line ends
for bash.  Something like this may help (please check the

  (add-to-list 'process-coding-system-alist '("bash" . cp850-unix))
