Why do I get all kinds of crazy characters in my emacs shell?

When I open a shell in emacs (M-x shell) it has trouble displaying many "normal" characters. I'm using Putty on Windows to connect to a linux server (a bash shell). I'm running emacs within Putty with "emacs -nw".

What causes this and how can I fix it?

For example,

Without emacs:

username@server:~/so$ ls -a
.  ..  bar.txt  foo.txt
username@server:~/so$

In emacs:

username@server:~/so$ ls -a
^[[0m^[[01;34m.^[[0m  ^[[01;34m..^[[0m  bar.txt  foo.txt
^[[musername@server:~/so$

What you're seeing are ANSI control sequences for colouring output.

Emacs actually has a number of different ways to access a shell. They each have strengths and weaknesses.

Instead of M-x shell, try M-x ansi-term. This supports ANSI colours out of the box and is likely the closest to a "regular terminal", e.g. PuTTY, Konsole or Gnome Terminal.
