Ubuntu 'ls' Colors on Mac

Brian Mathiyakom bio photo By Brian Mathiyakom

I’m experimenting with a Mac as a software development environment. My first problem was the Terminal. I don’t want a terminal that lacks file color coating. I want the directory colors (dircolors) that I have in my Ubuntu setup.

I want this:

Snow Leopard is a version of ls that doesn’t seem to support dir_colors. First, install dir_colors supported ls via Macports:

sudo port install coreutils +with_default_names

Verify the new ls command with:

ls --color

If the color flag works, we’re good.

Next, define the color settings for various filetypes using dircolors. I’m using the dircolors settings from Ubuntu 9.10 (karmic):

# LS_COLORS environment variable used by GNU ls with the --color option.

# 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 # no color code at all
#FILE 00 # regular file: use no color at all
RESET 0 # reset to "normal" color
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.)
HARDLINK 44;37 # regular file with more than one link
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, or non-stat'able file
SETUID 37;41 # file that is setuid (u+s)
SETGID 30;43 # file that is setgid (g+s)
CAPABILITY 30;41 # file with capability
STICKY_OTHER_WRITABLE 30;42 # dir that is sticky and other-writable (+t,o+w)
OTHER_WRITABLE 34;42 # dir that is other-writable (o+w) and not sticky
STICKY 37;44 # dir with the sticky bit set (+t) and not other-writable
# This is for files with execute permission:
EXEC 01;32
# 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
#.btm 01;32
#.bat 01;32
# Or if you want to colorize scripts even if they do not have the
# executable bit actually set.
#.sh 01;32
#.csh 01;32
 # archives or compressed (bright red)

Copy that into ~/.dir_colors. Add bash aliases for the dircolors in ~/.bashrc:

# colored highlighting is awesome
if [ "$TERM" != "dumb" ] && [ -x /opt/local/bin/dircolors ]; then
  eval "`dircolors -b ~/.dir_colors`"
  alias ls='ls --color=auto'
  #alias dir='ls --color=auto --format=vertical'
  #alias vdir='ls --color=auto --format=long'
 
  alias grep='grep --color=auto'
  alias fgrep='fgrep --color=auto'
  alias egrep='egrep --color=auto'
fi

Restart the shell and enjoy!
