According to the documentation and the source, color-ls-3.12, and
the installation, I have:

/etc/DIR_COLORS

# Configuration file for the color ls utility
# This file goes in the /etc directory, and must be world readable.
# You can copy this file to .dir_colors in your $HOME directory to override
# the system defaults.

# COLOR needs one of these arguments: 'tty' colorizes output to ttys, but not
# pipes. 'all' adds color characters to all output. 'none' shuts colorization
# off.
COLOR tty

# Below, there should be one TERM entry for each termtype that is colorizable
TERM linux
TERM console

It is not a distribution. It was started many years ago with Linux 0.99.
75 floppy disks from somewhere. I keep this machine updated to the
latest of everything and all sources for everything including _everything_
are updated and compiled to the latest 'C' headers/runtime libraries.

The color-ls is color-ls-3.12.

Here is the problem:

Now, if I do `ls >foo`, the contents of foo do not have the color escape
sequences in them. If I do `ls | more`, the same is true. Pipes and
redirections from my shell do not get the color escape sequences.

However, a shell spawned by 'make' seems to be different. I note
that anything requiring a '$$' instead of '$' seems to be affected.

Cheers,
Dick Johnson
