efaq: ^M in the shell buffer

 
 6.2 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 ($?INSIDE_EMACS && $?tcsh)
          unset edit
          stty -icrnl -onlcr -echo susp ^Z
      endif
 
    Or put this in your ‘.emacs_tcsh’ or ‘~/.emacs.d/init_tcsh.sh’ file:
 
      unset edit
      stty -icrnl -onlcr -echo susp ^Z
 
    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 customize the ‘comint-process-echoes’
 variable in your shell buffers, or try the following command in your
 shell start-up file:
 
      stty -icrnl -onlcr -echo susp ^Z
