Listing Colours For Dark Backgrounds

From: andrew cooke <andrew@...>

Date: Wed, 22 Jun 2011 19:19:20 -0400

On Unix (bash shell, at least), the colours displayed when you type "ls" can
be defined in a file called .dir_colors

When you have a dark background to your terminal the default colours are not
that readable (in particular, blue is hard to see - this is because your
eyes/brain are not very sensitive to that colour).

I use the following file, which uses red for directories.  It takes some
getting used to after the standard scheme, but works much better in the long
term.  I'm posting it here because I manager to lose an earlier version when
updating OSes.

Credits: file based on whatever was in OpenSuse, I would guess.


# 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.

# Extra command line options for ls go here.
# Basically these ones are:
#  -F = show '/' for dirs, '*' for executables, etc.
#  -T 0 = don't trust tab spacing when formatting ls output.

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