Colorindo seu terminal.

# 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

# 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.
#  -b = better support for special characters
OPTIONS -F -b -T 0
