I am running Cygwin as an Inferior Shell in Emacs. Here's the basic step I am following:

  • C-u M-x shell (rename the buffer to cygwin)
  • cd \cygwin
  • cygwin.bat

Here's what I see:

[32muser1@mymachine [33m~[0m

If I run cygwin.bat outside of emacs, it gives me:

user1@mymachine ~

I could almost deal with the extra characters, but when I try ls here's the result:

$ ls
bash: $'ls\r': command not found

I must be doing something wrong. Any suggestions?

EDIT: M-x ansi-color-for-comint-mode-on fixed the prompt, but the system is still not able to decode the ls command.

Here's the fix for the unix linefeed junk:

Basically, just run:

M-x set-buffer-process-coding-system

with 'undecided-unix and 'undecided-unix parameters.

Also, change the prompt to be:

export PS1="\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$"

The default PS1 causes ugly errors.
