I want to disable all color in my shell. Not ls, not nano, not vi, nothing. What's the best way to achieve this?

if you are using PUTTY to remotely access the shell, then:
- on the left panel, click Colors
- uncheck the three boxes on the right panel (they are checked by default)

I'll have to switch to a terminal program that lets me do this. Thanks. – Poe Apr 6 '11 at 1:57
Geekosaur's answer is better for you, really. – Slomojo Apr 6 '11 at 3:21
@slomojo his answer didn't work with my terminal client – Poe Apr 6 '11 at 9:46
Oh, interesting, which client is it? – Slomojo Apr 6 '11 at 10:37
I'm using iTerm (OS X) and still getting color if I export TERM=vt220, and in 'ls' even after unsetting LS_COLORS – Poe Apr 7 '11 at 3:42

unset LS_COLORS; export TERM=xterm should do it, or at least get you most of the way there. You may need to change that to say TERM=vt220 for some overly "smart" programs.

Definitely recommend VT220 over XTERM. – Slomojo Apr 6 '11 at 3:20
"xterm" is a color terminal, to disable colors you need TERM=xterm-mono – Idelic Apr 11 '11 at 21:37
xterm -cm

This will start an xterm with no colors.
