# IT APPEARS SUSE DOES NOT RESPECT THIS
#
# The keywords COLOR, OPTIONS, and EIGHTBIT (honored by the
# slackware version of dircolors) are recognized but ignored.

# Below are the color init strings for the basic file types. A color init
# string consists of one or more of the following numeric codes:
# Attribute codes:
# 00=none 01=bold 04=underscore 05=blink 07=reverse 08=concealed
# Text color codes:
# 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white
# Background color codes:
# 40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white
NORMAL 00	# global default, although everything should be something.
FILE 00 	# normal file
DIR 01;34 	# directory
LINK 01;36 	# symbolic link.  (If you set this to 'target' instead of a
           	# numerical value, the color is as for the file pointed to.)
FIFO 40;33	# pipe
SOCK 01;35	# socket
DOOR 01;35	# door
BLK 40;33;01	# block device driver
CHR 40;33;01 	# character device driver
ORPHAN 40;31;01 # symlink to nonexistent file

# This is for files with execute permission:
#EXEC 01;32  # Don't use bright green with brown background!
EXEC 01;32

# TEST_MARKER

# List any file extensions like '.gz' or '.tar' that you would like ls
# to colorize below. Put the extension, a space, and the color init string.
# (and any comments you want to add after a '#')

# If you use DOS-style suffixes, you may want to uncomment the following:
#.cmd 01;32 # executables (bright green)
#.exe 01;32
#.com 01;32

#! /bin/bash

# test-dircolors — Fine-tune your dircolors for unique colorings of any file type
#
# Author: Micah Elliott http://MicahElliott.com
#
# Tools like ls, tree, zsh color completion, etc make use of dircolors
# settings. This script will show you bunches of files, colored by
# their various extensions (or non-extension files like Makefile).
# Useful for tuning your console color scheme and grouping files by
# type. ls’s -X option is a nice way to group your file listings by
# extension.
#
# The philosophy behind this is that certain types of files are
# similar, and it’s nice to be able to see them as such. For example,
# you may want to color scripts in purple,
# Makefiles/Rakefiles/Gemfiles in yellow, logs in red, archives in
# blue, images in brown, configs in green, generated stuff in dark
# gray, and so on. Choose the categories that suit you (you’ve only
# got a handful of colors to work with) and run this repeatedly until
# you’re happy.
#
# See https://gist.github.com/718567 for an example xterm color
# scheme.
