Uncoloring ls (2019)

This is an update from "Uncoloring ls" which documents how to disable colored ls output on older systems which define that behavior in a profile.d script.

Some more recent systems load the colorization rules in a more generalized fashion. The load still occurs from a profile.d script, typically ls.bash, but mixed in with other functionality related to customizing the shell.

The newer profile.d script looks first for $HOME/.dir_colors, and if not found looks for /etc/DIR_COLORS.

To disable colorized ls for a specific user create an empty .dir_colors file.

touch $HOME/.dir_colors

Or to disable it for all users make the /etc/DIR_COLORS files not exist.

sudo mv /etc/DIR_COLORS /etc/DIR_COLORS.disabled
