How do I get rid of `^M' or echoed commands in my shell buffer?
===============================================================

   Try typing `M-x shell-strip-ctrl-m <RET>' while in `shell-mode' to
make them go away.  If that doesn't work, you have several options:

   For `tcsh', put this in your `.cshrc' (or `.tcshrc') file:

     if ($?EMACS) then
         if ("$EMACS" == t) then
             if ($?tcsh) unset edit
             stty nl
         endif
     endif

   Or put this in your `.emacs_tcsh' file:

     unset edit
     stty nl

   Alternatively, use `csh' in your shell buffers instead of `tcsh'.
One way is:

     (setq explicit-shell-file-name "/bin/csh")

and another is to do this in your `.cshrc' (or `.tcshrc') file:

     setenv ESHELL /bin/csh

(You must start Emacs over again with the environment variable properly
set for this to take effect.)

   You can also set the `ESHELL' environment variable in Emacs Lisp
with the following Lisp form,

     (setenv "ESHELL" "/bin/csh")

   The above solutions try to prevent the shell from producing the `^M'
characters in the first place.  If this is not possible (e.g., if you
use a Windows shell), you can get Emacs to remove these characters from
the buffer by adding this to your `.emacs' init file:

     (add-hook 'comint-output-filter-functions 'shell-strip-ctrl-m)

   On a related note: If your shell is echoing your input line in the
shell buffer, you might want to try the following command in your shell
start-up file:

     stty -icrnl -onlcr -echo susp ^Z
