incsearch stands for incremental search. It means that you will see what vim matches as you type in each letter of your search string (without having to hit return before search is even attempted).

dircolour setting

dircolors - Set color parameters for ls.
This is my dircolors for my linux machine You can copy and save it .dircolors in your home directory.

# 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.
OPTIONS -F -T 0

this is an incredibly useful object, one that can return all sorts of information about the logged-on user and the local computer.

The one drawback to this object is the fact that it can only be created locally: you can’t create an instance of ADSystemInfo on a remote computer and then get information about the user logged on to that machine.
